Oh no, it's Infernoburner again with his bad and useless suggestions! Hide in the closet!

So, here's the explanation for the Jelly Bomb:
The bomb would explode, leaving behind some slime on the ground, similarly to the Oil Jar when broken. Enemies that step on this would repetively take damage similarly to how Brambles and spikes work. The slime on the ground disappears after 2 seconds for the 2*, 3 for the 3*, 4 for the 4*, and 6 (Yes, 6) for the 5*.

Normal Line:
Jelly Bomb 2*
Description: A bomb that combines the delicious taste of jelly with some explosive powder.
Design: Pretty much same as the Jelly Shield, but in a ball shape.
Damage: Deals normal damage, about 5% stronger than a Shard Bomb (normal).

Spiked Jelly Bomb 3*
Description: A Jelly Bomb upgraded with Jelly spikes and cores to provide stronger damage.
Design: Same as above, taller, Brute Jelly Shield's crest but still pink.
Damage: Super Shard Bomb (3*), but 10% stronger.

Shankle N' Rock Bomb
Description: A bomb as annoying as a Shankle and as explosive as hard a Rock Jelly is.
Design: A big stone with spikes and with the Rock Jelly Crest on it.
Damage: Heavy Shard Bomb (4*), 15% stronger.

Jolly Green Bomb
Description: A bomb that explodes with the fury of the Jelly Green Giant.
Design: A huge, light green ball of slime with small dark green dots on the top. When detonated, a holographic Jelly Green Giant pops up like with Snarby and DBB.
Damage: 5* Shard Bomb, x15

Freeze Line:
Does piercing instead of normal and freezes monsters for 3-6 seconds. (Depends on star, 3 does 3, 4 does 4, and 5 does 6) Same damage as the current Sun Shards line, with 5% (2*) 10% (3*) and 15% (5* and 4*)

3* Hubert's Bomb
Desc: A bomb said to be made out of the spikes of Hubert, the friendly Jelly. (People who saw that Scenario Room will get it :D )
Design: A brute jelly helm-like sphere with some spikes and spikes attached to it.

4* Ice Cube Bomb
Desc: A bomb so cold you won't even feel it's in your hand. Take extra caution when detonating.
Design: A block of ice and spikes. Covers an 6 tile distance and has light blue

5* Impostoclaus Bomb
Desc: A bomb that Impostoclaus normally puts in the Winterfest presents of the naughty. Chromalisks hate him so much.
Design: A boulder of the red Impostoclaus-like slime. Covers an 8 tile distance and drops Impostoslime instead of freeze slime.

On to the Mortafire items:

The Mortafire Cannon would, without the shield, do small damage and fire rockets like a Rocket Puppy. They won't detect targets tough, and will do Supernova damage -%30.

Now why would you want such crap, would you ask. Let me explain.

Combined with the Shield, the rockets would deal Avenger -%5 damage, per missile with a clip of 4 rockets. Not only that, the Cannon would act way different while shielding. When you try to shield, your screen will zoom out and you will have the oppurtinity to shoot like the Mortafires and Roarmulus Twins do. The shield will, like the Mortafire's, be fully invicible, but here's the catch: Your sides and back will have full vulnerability and you won't be able to walk while in air-attack-shield-up mode. To go out of it, all you gotta do is release the the shield button and your Mortafire Cannon will be the cheap version of Supernova again. No charge attacks, the shield mode is kinda one.

The shield acts like a Plate Shield when not mixed with a Mortafire Cannon.

Both of these items would be 5* and are a rare drop from t3 Mortafires and Red Roarmulus Twins. They always drop together and apply to all party members. (Screw you, book, Humbug, and Darkfang)
No, I couldn't find a better way of receiving these. If you come up with a better way, I'm open.

Description for shield: An incredibly resistant shield that lets you shoot rockets into the sky without them destroying the roof. How the rockets do this however, is a mystery.

Description for Cannon: A bulky device made to shoot big bad rockets. Don't use it near nuclear explosives!

Clip waiting time for the launcher would be 3 seconds (glorp!).
Also, enemies like Wolvers, Devilites, and Gremlins won't dodge them. I never said anything about the big bad rest, tough... (Let's be honest here, Lumbers and Scuttlebots are dumb and fat. This would increase their IQ more than standing on a chair.)

I'm open for CONSTRUCTIVE critism, buffs and debuffs here and there.
