Squitter the Spider is an Animal Friend in the Donkey Kong franchise 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 franchise 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 four pairs of shoes Squitter wears resemble the one worn by Expresso the Ostrich, another Animal Friend, with the shoes worn by both characters having an orange and white color scheme.
 * While most real-world spiders produce silk from their backsides, Squitter is able to shoot it from his mouth. However, members of the spider family Scytodidae are actually able to spit harmful venom-infused silk from their chelicerae, and Squitter even resembles these spiders, as both have an orange coloration with dark spots.
