I think, that it could be Scat from Dink the little dinosaur in my case, because he, like Petrie, or Guido, is very nervous, quirky, paranoid, but overcomes his fears, when it is necessary, and one thing not particularly featured in LBT about Petrie and Guido, he also likes good food, which is quite similar to me too.
