Pak E. Derm

Pak Elephant Derm is an elephant in the game Yoshi's Story. The little elephant holds up a "Stop Sign" and doesn't let Yoshi pass. To pass, Yoshi had to Ground Pound the ground, and Pak E. Derm would fall on the ground, letting Yoshi pass. Yoshi had to pass quickly because he would get up soon. There seems to be more than one, according to the game and the story for the level. Yoshi enounters Pak E. Derm three times throughout the first level.

Pak E. Derm also appears in Super Smash Bros. Melee, as a trophy, and in the background of the Yoshi Story stage. According to the trophy thetre is only one, also according to the trophy he's been practicing the skill of holding the sign for years. It is unknown why he would take so long but it could refer to him having no arms but holding the sign anyways, or a joke to give him a more in depth explanation for his trophy other than "he stopped Yoshi from passing but he ground-pounded him to get pass".

Pak E. Derm's name is a play on "pachyderm", another name for an elephant.
