Rip Van Fish

A Rip Van Fish is a sleeping fish introduced in Super Mario World. It is a large blue fish with orange fins, tail and lips along with a pair of big eyes. If Mario swims too close to a Rip Van Fish, it will awaken and begin to chase him until he can put significant distance between them, at which point the fish will go back to sleep. However, if Mario is invincible, it will do the opposite and flee from him. It is unknown whether it is related to Cheep Cheeps, which they resemble.

Rip Van Fish is named after the literary character Rip Van Winkle, who fell asleep for twenty years.

In "King Scoopa Koopa", after leaping down a Warp Pipe in the Star Path to escape several cave people transformed into Chickadactyls, Mario and Princess Toadstool end-up in the ocean. Seeing several Rip Van Fish surrounding them, Mario and Princess Toadstool make a mad-dash to a nearby Warp Pipe, in the process, waking-up all the nearby Rip Van Fish. Fortunately, Mario and Princess Toadstool struck into the Warp Pipe before the Rip Van Fish can attack them.

In "Mama Luigi"; Luigi and Yoshi, after falling into the ocean, end-up waking a nearby Rip Van Fish, which proceeds to chase Luigi and Yoshi. Attempting to escape the Rip Van Fish, Luigi and Yoshi enter a nearby, underwater tunnel and begin swimming furiously, avoiding obstacles such as ? Blocks and Urchins.
