Squitter the Spider is a recurring Animal Friend that appeared in the Donkey Kong series. He is a giant, red spider with shoes on all eight of his legs that is an ally to the Kongs.
First appearing in Donkey Kong Country 2: Diddy's Kong Quest and reappearing in Donkey Kong Country 3: Dixie Kong's Double Trouble!, Squitter can be found and ridden on by breaking his Animal Crate. He has the ability to spit an unlimited amount of web projectiles from his mouth, which has a number of applications. The web projectiles can be aimed up or down, in addition to forward, and they can defeat enemies they hit. The webs can also form into platforms that Squitter and the Kongs can hop on, which can be used to cross wide gaps or climb up massive heights. These platforms are temporary however, so one must be quick.
Squitter appeared as one of the land animal buddies in the Wii racing game Donkey Kong Racing. Squitter is fast, but weak with average stamina. He has the ability to shoot webs which would traps and stops the foes in front of him.
