The Mermerang only made one appearance, in the episode "Shuffleboarding."
The Mermerang is red and has scales on it, like the costume from Mermaid Man. It is quite similar to a normal boomerang.
This weapon is one of Mermaid Man's weapons to defeat evil. SpongeBob keeps throwing it to Barnacle Boy, and it returns to SpongeBob. On one occasion, in "Shuffleboarding," he missed, and the Mermarang was a "run-away." It injured most of the seniors, along with Mermaid Man, and Barnacle Boy, and they in turn, had to go to the hospital. In one episode SpongeBob gets his hands on the Mermarang and doesn't understand its function, so accidentally hurts Mermaid Man and Barnacle Boy.
- It's a parody of a boomerang.
