i am thinking how there could be a danger mission for each monster family and there hasn't been a danger mission for slimes so i decided to suggest one.
Name of mission :suggest one!
Description
Spiral HQ's radar has sensed a part of the royal jelly palace has suddenly disappeared, spiral HQ had sent a team to investigate . the team reported that they saw hundreds of thousands of slimes, lichens, polyps and weird tentacles of goo. the team said that the slimes were all coming out of a black and purple lichen looking thing! suddenly thinly thing spiral HQ could hear was static. Spiral HQ would like you to investigate the part of the royal jelly palace!

(to be honest i think that description is really bad rate it /10 i wont mind i am really bad at story writing)

(there will only be slimes on this danger mission. i know that might be a horrible idea but my ideas a verry flexible) (sometimes)
(000 can you make a quicksilver version of toxilargo plz :) and bring slooms and oiler baron back :)
at the first level will actually be part of the royal jelly palace but than with the same textures it will be a palace but very different, first everywhere will be swarming with slimes, lichens ect. I am thinking of 5 arena battles (i don,t know what they are actually called) in between them there are just the usual fighting slimes.
the first arena battle will be basically first wave just normal jelly cubes maybe 6 the next wave will be 2 of each lichen (2 quicksilvers, 2 oilers and 2 toxigels), 5 jelly cubes, enough lichens to make a lichen colony and 3 silkwings. the third wave will be 9 jelly cubes, 3 of each lichen, enough lichens to make a giant lichen colony and 4 silkwings.

in between the first arena and the second arena will be lots of quicksilvers. (there will be shock traps on the ground) (but still other slimes too)

the second arena battle will be based on quicksilvers.(there will be shock traps on the floor that are always on) first wave - 5 quicksilvers, 4 jelly cubes
and a few lichens. second wave - 9 quicksilvers, 6 jelly cubes , a lichen cony and 4 silkwings third wave - 4 quicksilvers, 2 jelly cubes , 2 silkwings and if you can a toxilargo version of a quicksilver please :)

in between the second arena battle and the third arena battle will be lots of toxigels, there will be poisin traps on the floor
(the arena is exactly the same and the shock traps will be poison traps )
the third arena will be based on toxigels, each wave will be exactly like the second arena EXEPT the quicksilvers will be toxigels and the quicksilver version of the toxilargo will be a toxilargo

in between the third arena and the fourth there will be lots of oilers and fire traps.

the fourth arena will be incase you haven't realized yet will be based on oilers. everything is exactly the same as the 2nd and 3rd arena but the quicksilvers and the toxigels will be oilers, the floor traps will be fire traps and the toxilargo will be a oiler baron.

the last arena will have a area as big as a normal arena but there will be shock, poison, fire, and spike traps on EVERY tile on the floor so you have to keep moving around or you will get shocked, poisoned, burned or impaled by a trap if you stand still for too long. (the traps on the floor will change slowly and in wide areas so you have a reasonable amount of time and space before the traps change. on the left of the arena there will be an area like the one in compound 42 which holds a toxilargo version of a quicksilver and say 5 quicksilvers. on the other side there will be a toxilargo and 5 toxigels. up north there will be a oiler baron and 5 oilers and above that there will be a area with 1 toxilargo version of a quicksilver, 1 toxilargo, 1 oiler baron, 1 sloombargo (pretty please) and 1 pre made full sized giant lichen colony!
so each wave. wave 1 - 9 jelly cubes and 2 lichen colonies. second wave. the gate with the toxilargo version of a quicksilver opens and 3 silkwings spawn. once they are all dead the gate that holds the toxilargo opens and 3 silkwings spawn. once they are dead the gate with the oiler baron opens and 3 silkwings spawn. after they are all dead a giant lichen colony spawns and 5 jelly cubes spawn and 2 silkwings. after that the last gate opens and 5 silkwings spawn. all dead? to the boss battle!

now i know what you are saying it will be way too hard but feel free to put comments saying OMG THAT LAST WAVE IS IMPOSSIBLE. if you say that please put a reason like for example get rid of the sloombargo or get rid of some of the traps ect.

LAST BOSS Name insert name here ( put it in a comment :D )

arena - traps on the floor, the traps dont turn on untill i say.
appearance - a massive lichen colony,(not yet) the size of vana. it will be black like a void gel and it has big massive black spikes on it, the spots on the front of it will be purple, the thing will have 4 cores, 1 that seems to be burning, 1 buzzing with electricity, 1 that is with toxic and 1 that looks like a miniature black hole. (on the first few stages) the thing has black tentacles coming out if it like cables out of a computer. the tentacles connect to the roof, and floor.

stage 1 the thing is invincible and has tentacles coming out of it, firstly there are 3 giant lichen colonies wandering around and loads of jelly cubes but no quicksilvers, toxigels or oilers. there will be jelly cube spawners and NORMAL polyp spawners everywhere. once you kill the giant lichen colonies the tentacles will appear to have a lump inside them going into the thing, the lumps are glowing pink and the thing grows a bit bigger.

Stage 2 the thing now spawns loads of quicksilvers around it and quicksilver spawners appear and silver polyp spawners appear too.
the thing than spawns 2 equivalents of a toxilargo. now the shock trap turns on in a wave formation. killed the 2 equivalents of a toxilargo? the tentacles than get more lumps that go down/up to the thing and now they are glowing light bluey and they have shock effects around the lumps. and the thing grows a bit bigger and now when you get in contact with the thing you get shocked. and there are shock effects around the thing.

stage 3 the thing now spawns a load of toxigels and caustic polyps and toxigel and caustic polyp spawners appear, 2 toxilargo's spawn and the shock traps turn off and the poison traps turn on in a wave fasion. more jelly cubes spawn and lichens spawn lumps appear in the tentacles and this time they are glowing green and have toxic effects around it, the thing has toxic effects around it and if you get in contact with the thing you get poisoned (like anyone would care)

Stage 4, the poison traps turn off and the fire traps turn on in a wave fashion. the thing spawns 2 oiler barons and loads of lichens and jelly cubes, and lichen and jelly cube spawners. once you killed the oiler barons the tentacles get a lump and this time they are glowing red with fire effects.

Stage 5 there is a bright flash like the one when you start the RT battle and jelly cubes, lichens, and spawners disappear (if i have missed something please say) the thing is now the size of vana and this is where the real battle begins !

attacks
(every time you get hurt by the thing there is a 33.33 chance of getting shocked poisoned or burned.)
tackle - usual tackle.
spin attack - spins around knocking back players and sending 10-12 spikes in a ring fashion.
lunge - only lunges at the edge of the arena the thing lunges all the way to the other side of the arena.
dig - goes down and where it travels it creates a wall of any polyps
Spike - sends up 12-15 spikes up (like a giant lichen colony)
spawn tentacle - spawns 4-8 goo tentacles with spikes on the end of them - the tentacles act similar as cables (from ghosts in the machine)
Spawn Slime - spawns 5-10 jelly cube.
Spawn lichen - spawns 4-8 lichens
spawn oiler - spawns 3-5 oilers and a oiler baron - also activates the fire traps
Spawn Quicksilver - spawns 3-5 quicksilvers and a quicksilver equivalent of a toxilargo - also activates shock traps
Spawn toxigel - spawns 3-5 toxigels and a toxilargo - also activates poison traps

Stage 6!

the thing is now smaller and it does its attacks quicker
Attacks
Tackle
Spin attack 15-18 spikes
lunge - much faster lunge
dig - way faster
Spike - 15-18
tentacle - 8-12
spawn jelly cube - 10-12
spawn lichen - lichen colony
spawn quicksilver - 5-8
spawn toxigel - 5-8
spawn oiler - 5-8

Final Stage!!! (stage 7)
The thing is now the size of a giant lichen colony
even faster
now each hit will get 2 random status effects

Lunge super speed!
Dig - doesn't spawn polyps instead spikes like snarby
Spike - 20-24
Spin attack - 20-26
Spawn EVERYTHING spawns all of the things that is can spawn in 3 seconds!
Super spike - 30-40 - spikes on the entire arena!
Tentacle web - 2-4 spawns tentacles that stretch from 1 side of the arena to the other on contact get random status effect lasts 4-5 secs
Melt - 2-6 Melts into the ground and erupts in a gyres of black slime than body-slams back down stunning
split - 2-3 splits into smaller bits and each bit runs around doing spin attacks - 5-7 than joins back together
Thunderstorm - 2-4 places away from the thing and you a grey mist starts building up, there are flashes of lightning in it, if you step in it you get shocked. after a while there is a loud clap of thunder and if you are close enough you get pushed back and stunned, after the thunder a quicksilver equivalent of a toxilargo and 2-4 quicksilvers. note that there are multiple clouds which could make 4 quicksilver equivalent's of a toxilargo and 16 quicksilvers. this move is MOSTLY used when your average health is around half
Poison geyser - patches on the ground that are 4x4-5x5 start bubbling, than loads of horrible poisonous gloop spreads out going everywhere. if you are in the 4x4-5x5 area where the geyser started you get a lot of damage and poisoned. when the gloop has spreaded out you will find a toxilargo and 2-4 toxigels! this move is MOSTLY used when your health is low
Lava wave - 2-4 areas will start to turn red like it was burned and will than burst into flames. there will than be lava flowing outwards a fairly long distance that will burn you like a fire trap but it is easily shielded after the lava disappears you will find a oiler baron and 2-4 oilers!
oil spill - the thing will cover 60% of the arena and than the fire traps will turn on catching flames the thing only uses this move when your party's average health is between 100% and 66% health is between 33% and 66%
Poison gas - bubbles will start forming on the arena! they do no damage but poison you. the thing only uses this move if your party's average health is below 33%
shock wave - the thing will cover 60% of the arena a shocking cloud that will only shock you. the thing will only use this move if your party's average health is between 33% and 66%

if you think it is overpowered, unfair, too easy, sounds boring than put in the comments how i could improve it k
