Scaredy Rats, sometimes mistaken as Little Mousers are enemies in New Super Mario Bros. Wii and in Mario Party 9. They are rat-like creatures with big black eyes with pink pupils, a pointed snout with an orange nose, big ears, small orange feet and a small, skinny tail. Scaredy Rats only appear in World 4's Ghost House. Here, they appear just appear march on the mostly wavy-shaped floor. However, when Mario and the crew (Luigi, Blue Toad, and Yellow Toad) near them, they will stop and jump in place. However, when one member of the large line of Rats (there are several lines of Rats in the Ghost House) is jumped on, all the other members of the large line will run away in panic. Scaredy Rats can be defeated by jumping on them or by freezing them with the Ice Flower's/Penguin Suit's powers and then Ground Pounding the Ice Block they are trapped in. In 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 will steal some Mini Stars from each player before destroys each turn some spaces ahead. The current captain must choose a player to roll a Dice Block. The player who actually reaches the Scaredy Rat defeats it and receives all the Mini Stars it stole.
