The Boomerang Pet Ball is a toy that SpongeBob buys for Gary in the episode "Gary Takes a Bath" and the book Meow...Like a Snail?!
Description[]
It comes in a small teal box with a label that reads "New Boomerang Pet Ball. Really Works!," with the word "new" imprinted in light green text within a dark green explosion banner, the words "boomerang pet ball" in white text within a dark red wide diagonal line across the box, and the words "really works" in yellow text within a small brown line.
The ball itself is an orange squidgy ball that has the properties of a boomerang, despite not being shaped like one. Although it appears as a cheap novelty toy, the ball, in fact, does work as promised by the box. Oddly, the box itself also functions as a boomerang.
Role in episode[]
When SpongeBob attempts to get Gary to take a bath, he throws the ball towards the bathtub. However, the ball comes back to him. In frustration, SpongeBob throws the box, but it too comes back and hits him on the head when he begins to walk away, knocking him out.
