Squitter the Spider is an Animal Buddy in the Donkey Kong series who first appears in Donkey Kong Country 2: Diddy's Kong Quest; he is a large spider covered in orange and black hair which has a vague resemblance to lava.

Donkey Kong Country 2: Diddy's Kong Quest
In Donkey Kong Country 2: Diddy's Kong Quest, Squitter can shoot webbing from his mouth, either as a projectile to hurt enemies or to make temporary platforms that can be used to reach high areas or cross gaps; however, he cannot jump on enemies and his jumping ability is actually worse than the Kongs.

Levels: Squitter has a level dedicated to him in Donkey Kong Country 2: Diddy's Kong Quest (Web Woods), which makes frequent use of his ability to spin web platforms.

Trivia

 * Squitter is one of the few spiders in the Donkey Kong games to actually have eight legs, whereas most others simply have six. Despite this, Squitter still lacks some spider features, such as multiple eyes and chelicerae.
 * The eight pairs of shoes Squitter wears resemble the one worn by Expresso the Ostrich, another Animal Buddy, with the shoes worn by both characters having an orange and white color scheme.
 * Squitter's name is referred to on Grunty's Tower of Tragedy quiz in Banjo-Tooie, another Rare game, as one of the possible (wrong) answers to the question What is blocking the vents in Grunty Industries' Sewer System?.
