Adventure Time Art Submission: Lemon Grab

Over in We Love Fine, there is a T shirt design contest based on Adventure Time characters.  This is one of my submissions.  
Lemon Grab is one of my favorite characters from the show.  He has a terribly shrill voice and he is always uptight and high strung.  And he has some really memorable one liners.  Costarring on the design is The Thing of the Fantastic Four.  I know that I said I will never draw the Thing again, but I had a fun time drawing him as a cartoon.
I drew this with a Papermate Flair medium size marker and a Staedtler Mars Graphic art pen with a .03 cm tip for the Thing's rock lines.
