OrangStand

Orangstand (Palmus Walkum) is one of Lanky Kong's special abilities in Donkey Kong 64, learned by purchasing a potion at Cranky Kong's lab at Angry Aztec for three Banana Coins.

By pressing and holding the button while hitting the  button, Lanky will perform a handstand and walk on his hands, enabling him to scale steep slopes he could not otherwise.

An enhancement of this ability, Orangstand Sprint, is later learned by Cranky in Crystal Caves.

Trivia

 * The Orangstand is similar to the Talon Trot ability used in Banjo-Kazooie, another game created by Rareware.
