..site's still kicking, I see..well here's a necrobump from hell.
It's called Munchie. It's about this new kid in town who gets bullied in school until he meets Munchie, this magical gremlin-looking monster that can make pizza fly and sounds like Snagglepuss if he was Dom DeLuise in disguise.
Munchie helps the kid reclaim control of his life in his new environment, and the kid becomes popular enough for people to actually show up at his party he's hosting. It was also Jennifer Love Hewitt's first movie (she played said love interest).
