Esmarty is one of Bob's friends. He is generally laid-back, slimy, kind and always sick. He usually has a running nose. Like most of the boys he likes Stella Jackson but does not really talk about it. Also he is a secret rock stars slayer.
- His name is a play off of the words "Escargot" (French cooked snails) and the name "Marty".
- He leaves green slime whenever he walks.
- His name is briefly seen in the yearbook.
- He seems to be the only boy to not have manly breast.
- Vanilla gives him pep.
Esmarty sounds like Jake from Adventure Time, because they both voiced by John DiMaggio.
