Game	Banjo-Tooie
World	Jolly Roger's Lagoon
Color	Yellow
Use	Allows Banjo and Kazooie to breathe underwater

Oxygenate Water (also known as Sunlight) is the spell that Mumbo Jumbo uses in Jolly Roger's Lagoon. Because Jolly Roger's Lagoon is mostly underwater, Banjo and Kazooie's medium-sized air bar is not strong enough to keep them alive while swimming underwater. Instead, when they give Mumbo a Glowbo, he casts a spell on the entire lagoon by using the sun to "oxygenate" the water - allowing Banjo and Kazooie to explore underwater without needing to return to the surface for air.
