Swellbelly

Swellbelly is an enemy in Banjo-Tooie. A large blowfish 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 which cover its body. Swellbellies can easily be defeated by using the Talon Torpedo, or by firing Grenade Eggs at them once underwater egg aiming has been learned.
