However, when Felix proves to be an incompetent, asthmatic (and unsuitably kind-hearted) human, the monsters plot to eliminate him and gain control of the secret formula. Over time, Francesca develops feelings for Felix after he unknowingly saves her multiple times. As Dracula, Frankenstein's Monster, and the Monster's Mate descend upon Francesca, she sends out a letter (via messenger bat) to an unknown recipient. When the monsters corner Felix upon capturing Francesca, they are frightened at the arrival of "It" (revealed to be a giant gorilla and a take-off of King Kong) who proceeds to go on a rampage since he was not invited. "It" snatches up the monsters and Francesca (on whom "It" develops a crush).
