Peepa

Peepa appeared in 2011 video game called Super Mario 3D Land. Peepas are Boo enemies debuting in Super Mario 3D Land. They are small, white ghosts with stubby arms, black eyes with white pupils and a permanently smiling mouth which shows its two teeth. As ghostly enemies that have an appearance different from most Boos and often travel in predetermined paths, Peepas are somewhat similar to the Eeries in Super Mario World.
