OMG is this new? Sentry guns!

So I was at the current jelly gate, the Ruby knight gate, and there was this box near the party button.
It said to give 5 energy, and I did.
And then the box turned in a turret, then when we stepped on the party button, a bunch of spiked jellies spawned in a box, then shot a bunch of blue lasers at the jelly.
I believe it was aurora isles jelly farm, not sure which jelly farm though.
Here's some screenies :D

Lol. I thought I had found something new.
Well, there pretty cool.

"Lol. I thought I had found something new."
Yeah...sorry to be the one to bum you out.
"Well, there pretty cool."
Yes, yes they are, maybe not worth the 5e if you're properly geared, but anytime is fun to watch it FIRE IT LAHZORS.

When you have ele passes, anythin's worth it, especially when you got vortexes, yo.
Took this one a week or two ago and just let the lasers do the talkin'.

Mecha Turret: I'MA FIRING MY LAZOR BLARGH!!!
*20 Jellies splattered!*

It's in Jelly Farm II, big waste of 5 CE if you ask me...
Only amuses the first time

Its one of those things i would never check out if i wouldnt have elevator pass.

I find them equally amusing every time I power one up and see it silently go "Pshewww!" and splatter some jellies.
Practically? Not worth the five energy.
For entertainment's sake? Hell yeah, fill it up!
I think sentries should appear more often in the game, they're brilliant.
Been there for ages, sorry to burst your bubble.
But I have to admit, although not entirely practical, they ARE a whole ton of fun to use.
would be better if it was a usable turret though :D
