Transformation

In the Banjo-Kazooie series, there are magic users that can alter various things, including Banjo and Kazooie's form. This is a list of those spells and transformations.

Generally, a transformation allows Banjo and Kazooie to either fit into a group of like members (such as becoming a walrus to befriend another walrus), to tackle obstacles otherwise unscaleable (such as a snowball growing bigger to activate a large switch), or to enter areas that bears and birds cannot access (such as mechanical-personnel-only doors).

Banjo-Kazooie
In Banjo-Kazooie, all transformations are all immune to damaging terrain, can all fit in small spaces, and can all climb slopes too steep for even the Talon Trot. Most transformations cannot attack, and most of them can walk underwater with no need for air. Transformations cost Mumbo Tokens to unlock and cannot travel very far outside of a world's entrance before the spell must be undone.

Banjo-Tooie
In Banjo-Tooie, transformations cannot exit their host world. Most of them can attack and have varying amounts of health.

Also, each world in Banjo-Tooie has a certain spell that can be performed by using Mumbo Pads. Some spells can be used only once, while others can be used as many times as necessary.

Banjo-Kazooie: Grunty's Revenge
Transformations in Banjo-Kazooie: Grunty's Revenge are in a similar vein as those from Banjo-Tooie since most can attack. However, the transformation system allows any transformation to be used in any world provided it is used in the original world first.
