The Pink Box

The Pink Box is an anomaly where a pink box can appear somewhere in Super Mario 64, similarly to the Purple Box. However, instead of summoning harmful anomalies, it simply spawns Hoot the Owl. This version of Hoot the Owl eventually drops the player and flies back to the original location of the Pink Box. This usually signifies significantly more personalized copies, similarly to the White-Eyed Chain Chomp.

Hoot's Tall Tree
Hoot's Tall Tree is the level where the Pink Box can be unlocked. It is described as taking place in the sky on a tree stretching up very high above the clouds. There are several branches that have to be climbed, some only being accessible using Hoot due to large gaps. There are also various invisible walls around the level to stop the player from cheating. At the top of the tree, a pink Cap Switch is present that can be pressed to unlock the Pink Box permanently. There is also a red coin star.
