Brute jellies will be in the slime family, and like all other slimes it will do piercing damage. It's blue, and it is shaped like a sphere with a darker nucleus in the middle. It's normal attack consists of two parts:
1: It lurches forward and attacks like any other jelly.

2: It consecutively slams forward a little farther, but this time it can cause stun.

It's special will be like the quicksilver's

It bobs up and down, to show that it's about to unleash it's special, then bounces everywhere like the quicksilver, but it causes stun instead.

Tier 1: It's shaped like a sphere, and only has the 2-hit normal Attack.

Tier 2: It's a sphere with 2 rounded spike protrusions on the side, has the 2-hit normal Attack AND the special.

Tier 3: It's a sphere with round protrusions in the formation of a sphere around 2 large spikes on the side. It has the 2-hit normal Attack AND the special AND on the second hit of it's normal attack it causes sleep instead.
