Arachnichimp are from planet Aranhaschimmia. They are blue colored chimpanzee-like aliens with 4 arms, 4 eyes and two legs. They can spin webs from their tail and are very agile. They also climb walls. Their diet is unknown, it is shown that they spin giant sticky webs like spiders. It seems they have a monarchy.
Using the Ultimatrix evolutionary feature, Arachnichimps lose their extra pair of arms, but gain two pairs of spider-legs, have gorilla-like bodies, are black and indigo in color, have different looks to their eyes and have an extra pair of eyes, making it six eyes rather than four. They also shoot webs from their mouths and are super strong.
