I remember very little about this movie, but I saw it a long time ago so I know it is at least older than me. The main character is some random nerd guy who gets picked on by some other blonde guy in a Hawaiian shirt, I THINK. The main character was at a diner when he someone threw a pie in his face and laughed at by everyone. He later becomes the hero of the movie when a vampire creature starts terrorizing his town.
The end of the movie takes place in a mansion where a tiger or maybe a werewolf is loose in the hallways. The tiger gets impaled by a spear and transforms into the blonde guy from earlier in the movie. Finally the main villain who is apparently a vampire turns into a giant ugly bat creature, but the main character man tears off the curtains of a giant window and the vampire explodes. This was a strange movie and it was pretty corny.
