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 Bunch Coins.
By pressing and holding the 
button while tapping 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 Lanky in Crystal Caves, which allows a faster running speed.
