Thumb

Thumb is a contestant currently competing in Dumb-Ass Monchrome People.

Personality
Thumb is generally quite grumpy. He complains about a lot of things. Phlegm took a liking to him and Thumb didn't really oppose the idea of her company, so they are now friends. Thumb uses Phlegm as an outlet to voice his distaste for whatever he dislikes and Phlegm is happy to sit and listen.

Fun Fact: Thumb is secretly glad Phlegm cannot talk, as he worries their personalities would clash too much if she could.

Trivia

 * Thumb is the only member of his team and the only male contestant to have legs but not arms
