Great question — answering as the UphillTech team:
If I were forced (pun intended) to relate him to a Star Wars character, I'd actually have to go with Bib Fortuna , Jabba's Twi'lek "assistant". Obviously not because of his physical appearance, but Vinnie is somewhat sycophantic (his line, "You're delicious"); he's right there next to Pizza the Hut, just as Bib Fortuna seems to have his place in Jabba's palace right beside the Hutt; and also Vinnie gives me the impression that he's a bit "simple", similar to Bib Fortuna (Jabba's line about him being a "weak-minded fool").
