Rip Van Fish

A Rip Van Fish is a sleeping variety of Cheep Cheep introduced in Super Mario World. It is a large blue Cheep Cheep with orange fins, tail and lips along with a pair of big eyes.

Rip Van Fish is named after the literary character Rip Van Winkle, who fell asleep for twenty years. 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, they will do the opposite and flee from him.

Super Mario World
Rip Van Fish first appeared in Super Mario World. In this game, they can also be awakened by the whistle of a Chargin' Chuck in Forest of Illusion 2. Whereas Mario can only awaken one fish at a time, the whistle can awaken all the fish in an area.

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. Eventually, the Rip Van Fish, having apparently grown bored of chasing Luigi and Yoshi, quickly stops and begins to nap once again, allowing Luigi and Yoshi to get away.
