Screaming Many-Headed Slime Alien on a Strange Planet Hat
Main Tag:  

Description: A giant green slime blob covered in pink spots towers over a bluish alien landscape with jagged rock spires. Long wobbly necks sprout from its body, each ending in a screaming antenna-topped head, some wearing purple, orange and curly yellow wigs. One neck ends in nothing but a foot. Chaotic, gross and hilarious.
