Palette Challenges! :)

[MagikMasterMind]

Hey everyone,

It's time we have a real challenge thread. I will give specific palette restrictions and requirements (theme, size etc). I will try to give updates every once in a while/new challenges

Note:
-You can make more than 1 attemp/submission per challenge
-Animation are allowed, as long as they follow the rules
-You can only use the colors in the challenge's palette restrictions!
-The image size can be bigger, but not smaller

First challenge:

Dimensions: 150 x 180
Palette:

Theme: Your ugly, evil, slimey creature
