Slim (Pixl)

Slim is one of the many Pixl creatures in the Wii video game Super Paper Mario. His special ability is to allow Mario to become very thin, letting him have access to previously inaccessible areas. An example of this would be if he wanted to get between two rails. Also if you stand still using his ability, you become invisible. His name was revealed at GDC, along with Boomer.

Trivia

 * His ability can be used without a partner in Paper Mario: The Thousand-Year Door.
 * He can't count to ten correctly, thinking this is how you do it:"One, two, five, four, Seventeen, 3.14, a marzillion, ten!"
