Cool Cubed Slushy is an ice-syrup drink mix introduced in the episode "Cool Cubed." It is referred to as a "slurpee" in general, but it is very different from a normal slurpee in many ways. In "Cool Cubed", the Cool Cubed creature serves as the main antagonist alongside the Translator. When Mordecai and Rigby go inside of Thomas's head to melt his brain core, the Cool Cubed attempts to freeze the core. Right when Cool Cubed jumps into the core, Mordecai successfully shoots an arrow at him. This causes him to melt in the brain core.
