A blue Sammer Guy.

Sammer Guys are creatures found in Sammer's Kingdom for the Wii video game Super Paper Mario. In the game there are exactly one hundred of them in all, each one guarding a gate to King Sammer. Each individual one has a unique name that is usually a pun on a Mario character, item or species (such as "Belly of the Yoshi"). As the player progresses through the level they'll be required to fight increasingly challenging Sammer Guys. In all there are twelve different types of Sammer Guys, each with their own special abilities.
