|World(s)||Jolly Roger's Lagoon|
- “Hurry up with the pool, I think I can feel a third leg starting to grow...”
- —Trotty, Banjo-Tooie
Trotty is a pig child found at Jolly Roger's Lagoon in Banjo-Tooie, and he has a friend named Piggles. While playing in a pool, Trotty grew a third arm on his left side, as a side-effect from the toxic waste from Grunty Industries.
In the game, Trotty claims that he grew a third arm because Piggles pushed him into the pool. He says he's quite sensitive about it, to which Kazooie calls him a "freako." He urges Banjo and Kazooie to clean the pool, as he can feel a "third leg" growing. When the duo heat up the pool, Trotty thanks them, but he then says that he does not want more arms. Kazooie then asks him "why not," as with three more he "could be Spider Boy."
- In the Japanese versions of the original Banjo-Tooie, Trotty only has two arms. The reasoning for this change is unknown.
