Cheep-Cheep School

Cheep-Cheep Schools are groups of Cheep-Cheeps first appearing in New Super Mario Bros. Wii. Cheep-Cheep Schools are composed of Yellow Cheep-Cheep's that are (besides the color) identical to normal Cheep-Cheeps, and can be defeated in exactly the same way: fire, ice, and Starman. They are not hard to get past because if Mario, Luigi, Blue Toad or/and Yellow Toad comes near, they split into two groups, Allowing the player to swim through them without taking damage.
