Hoot

Hoot the Owl is a nocturnal owl who sleeps in a tree near Whomp's Fortress in Super Mario 64 and Super Mario 64 DS. When Mario climbs into his tree, Hoot will offer to give Mario a ride to the top of the fortress. He later appears at Tall Tall Mountain. He also appears as an unlucky gambler in Mario Party Advance.

Hoot is very similar to the Heavy Zeds from Super Mario Land 2: Six Golden Coins and the generically-named owls of Wario Land II in that all these characters are sleeping owls who will help the game's protagonist when awoken.
