In the real world he appears as a normal-sized computer with eyes at the bottom of the frame and has images on the screen whenever he thinks of something. He also has a keyboard that's keys change colors multiple times throught his episode. His left hand appears to be able to change into a pointer or an hourglass. When he gets angered he has bloodshot eyes and his hands turn into red wires shaped like human hands.
When inside his digital world he has wire legs with computer mice for feet. Colin also uses the keyboard as a torso.
He is arrogant, brags about how he is supposedly "clever" and likes to sing about computers and the internet. However, while doing this he doesn't like being touched. He also seems to be interruptive. Sometimes he ignores questions posed toward him, preferring to talk about himself, or the "digital world". He likes gathering personal information and seems to be obsessed with oats, continuously showing them to the puppets.
