The Mermerang is light red-orange and has scales on it, like Mermaid Man's costume. It is quite similar to a normal boomerang.

Role in series

"Mermaid Man and Barnacle Boy III"

It is one of the weapons on the wall of weapons.


SpongeBob keeps throwing the Mermarang to Barnacle Boy, and it returns to himself. On one occasion, he misses and the Mermarang is a "run-away." It injures most of the seniors, along with Mermaid Man and Barnacle Boy, which sends them to the hospital.

"Appointment TV"

It is seen framed and put on display as part of SpongeBob's collection of Mermaid Man memorabilia.


  • It is a parody of a boomerang, and is also a parody of Batman's batarang due to being a boomerang weapon used by a superhero.
