Swellbelly

Swellbelly is a large blowfish enemy which inhabits the depths of Jolly Roger's Lagoon. It reacts to threats by puffing itself up to an enormous size, piercing anything that gets too close with the sharp spines that cover its body.

Swellbellies can be easily defeated by using the Talon Torpedo or by firing Grenade Eggs at them once Banjo and Kazooie learn how to use Sub-Aqua Egg Aiming underwater.

Trivia

• The models used for the Swellbellies were recycled from the Puftups in Donkey Kong 64 (also developed by Rare), except the skins have been re-colored.
