Squirm

Squirm is a caterpillar-like Toon with six body segments, which alternates in color between blue and mint. He features antennae on top of his head, which are also colored mint. The second segment of his body is shaped like a dewlap, while the third, fourth, and fifth segments of his body have a pair of limbs. His limbs are a greenish-yellowish color, the same color as the heart shaped part of his face. He also has three dark green freckles on his cheeks and droopy eyes, often with a squiggly frown on his face

Squirm can be described as pessimistic, and openly self-deprecating. He can be seen as immature, though in a much more self-deprecating way, compared to most other Toons' spirited or composed attitudes. He has persistent anxiety which can go as far to the point of even screaming and/or crying if he gets very emotional, expressed by his tendency to sniffle a lot during his elevator interactions with other Toons and his own dialogues when descending to another Floor. He’s also known to get awkward at moments, like when he gets a hug from Goob Render Goob, or invited to scrapbook with Flyte Render Flyte.

As seen by his interaction with Shelly Render Shelly, Squirm describes himself as "useless", nearing tears most of the time when he gets even slightly upset and even agrees with Shrimpo in their dialogue together when Shrimpo berates him. It's also notable that he has an appetite for books, which could be the reason he is banned from Brightney Render Brightney's book club (mentioned in their dialogue), and also that eating books is his coping mechanism. Squirm is also extremely sensitive, especially to inadvertent insults; shown in his conversation with Yatta Render Yatta.

Aside from the surface, he appears to have a crisis involving his identity, as seen in his interaction with Flutter Render Flutter and Dyle Render Dyle's Gossip about him. He sees himself as a caterpillar, with Flutter being implied to agree with this (likely due to her also being an insect from the lepidoptera order), however he was assigned as a bookworm by Arthur, believing that a "bookworm" is a type of worm rather than larvae. Shrimpo additionally insults him for not looking like a worm, which seems to only amplify his identity conflict.

Squirm seems to be hesitant in doing things he's not certain of, this proves to be a fact with his interaction with Gigi Render Gigi. Because he is always so tense, Squirm also can overthink things. This proves to be a fact with his dialogues when descending
