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 unscalable as a bear and bird (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.

World	Transformation	Unique Abilities
Mumbo's Mountain	Termite	Can stick to steep surfaces that Kazooie cannot
Bubblegloop Swamp	Crocodile	Can attack by biting, wade through the piranha infested waters, and play the Mr. Vile's mini-game.
Freezeezy Peak	Walrus	Can swim in frozen water, race Boggy for the first time, and allows you to enter Wozza's Cave
Mad Monster Mansion	Pumpkin	Can squeeze through tight spaces
Click Clock Wood	Bee	Can fly anywhere and land on plants Banjo can't step on

Banjo-Tooie

In Banjo-Tooie, transformations cannot exit their host world (with the exception of the Stony, which can enter Hailfire Peaks, and Dragon Kazooie, which can enter any world). Each of them are able to defend themselves (except the baby T-Rex), and many of them can attack. The transformations have varying amounts of health, which, in most cases, is also affected by the amount of energy segments you gained from Honey B.

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.
