Scaredy Rat

A Scaredy Rat is a white mouse creature that first appeared in New Super Mario Bros. Wii. They appear to have black sclera, red pupils, orange feet and huge buck teeth. They slightly resemble Little Mousers.

New Super Mario Bros. Wii
Scaredy Rats reappear in the game New Super Mario Bros. Wii where they are found in Ghost Houses. They are troublesome and run quite fast. When Mario or a teammate approaches, they stop scuttling and start jumping in place. When the player leaves, the Mousers continue scuttling. If one is stomped, all nearby Scaredy Rats will run in panic.

Mario Party 9
A Scaredy Rat appears in a Captain Event known as Scaredy Rat Race, on the board Boo's Horror Castle. The Scaredy Rat steals some Mini Stars from each player and scuttles each turn some spaces ahead. The current captain has to choose a player who must roll a Dice Block. The player who actually reaches the Scaredy Rat defeats it and receives all the Mini Stars the Scaredy Rat has stolen.

Trivia

 * The name Scaredy Rat is a pun on the term scaredy cat, which is a childish term for a coward.
