Japanese Fighting Fish

The Japanese Fighting Fish are characters from Planet Sketch.

The Sketch
The three fish (claiming to be "hard" Japanese fighting fish) bully another (typically much larger) fish, or another sea creature or an item, that is cohabiting in the same tank, only for the other fish, object or sea creature to retaliate in kind. In Season 2, this concept has been removed.

Character Description
The three fish wear white headbands with red circles. They look similar, except for their skin color. The orange fish is Robbie, the red fish is Mac, and the green fish is Billy.
