T-Rex Banjo

Promised by Mumbo Jumbo in Banjo-Kazooie, Banjo is transformed into the most fearsome and famous of the dinosaurs: Tyrannosaurus rex. However, at first, he may only become a Baby T-Rex; once Mumbo casts Enlarge on Humba Wumba's Wigwam, Banjo can transform into a Daddy T-Rex, which is much more loyal to the image of an enormous, terrifying beast. Each size is better suited to different tasks around Terrydactyland, each with different strengths and weaknesses. Both also must be used to activate certain switches pertaining to each of them.

Baby T-rex
As the smaller dino, Banjo is able to fit into certain places and speak with other dinosaurs. He may also use a roar to frighten off some mean cavemen. He is around Banjo's size, or maybe a little bigger.

Daddy T-rex
The transformation that dino lovers, macro-furs, and Godzilla fans have been waiting for since they entered the level, the larger T-rex form is MUCH larger. He is so large, he really can only fit in the main outside area. His roar is powerful enough to defeat enemies, and he's so big, he is able to defeat some enemies just by stepping on them. He is able to frighten the braver mean cavemen that the Baby form could not. He is about as big as a cliff, and, a little surprisingly, Banjo's shorts are still intact (albeit with a tailhole) and as tight-fitting as ever. The one downside to this form is that he's too big to use warp pads, which can be a pain if want to change back but get lost.
