The potion is a green chemical and is in a conical flask.
Role in the episode[]
As its name implies, it causes permanent paralysis in any living being. Finn and Jake decide to spray the potion on some imperfect tarts after stuffing them into an anti-gravity tote chamber. They then carry the tainted tarts by accident, serving the original purpose Finn intended: to paralyze potential tart thieves. In the end, the paralysis takes effect, as the Butterfly With Laser Gun is seen drifting away motionless after eating a tainted tart. It is likely that Grimby and Taddle were also paralyzed.
