T-Rex Banjo

T-Rex Banjo is Banjo's transformation in Terrydactyland from Banjo-Tooie, allowing him to transform into a Tyrannosaurus rex.

This transformation is unique in that it comes in two forms. The default form is a small dinosaur named Baby T-Rex. By having Mumbo Jumbo cast Enlarge on Wumba's Wigwam, Banjo can transform into a much larger dinosaur called Daddy T-Rex. Each size has its advantages and disadvantages, and associated puzzles.

In Banjo-Kazooie: Nuts & Bolts, the Daddy T-Rex appears in a glass case in Banjoland.

Baby T-Rex
The Baby T-Rex is roughly the same size as Banjo. It is able to fit into certain places, and the Bargosaurus won't attack (although they still cause damage upon contact). By talking to any Bargosaurus, Baby T-Rex Banjo will learn to roar, which can be used to enter doors with the Baby T-Rex face on it. However, this form has a smaller life bar than Banjo, and has no form of defense.

Daddy T-Rex
The Daddy T-Rex is very large, and he can only move around in the main outdoor area. He can defeat enemies by roaring, stepping on them, or eating them. He is able to frighten the braver cavemen that the Baby form could not. However, he is unable to use Warp Pads.

Trivia

 * This transformation was mentioned by Mumbo Jumbo in Banjo-Kazooie.
 * The Daddy T-Rex has an oxygen bar, despite being larger than any of the water bodies it can access in Terrydactyland. It is possible that Rareware had intended for the Daddy T-Rex to explore larger bodies of water, but scrapped the idea.
