When Billy decides he wants to grow up to be like Grim, he says nothing will stand in the way of their friendship. They meet a girl named Blandy, who looks very much like Billy, and Billy falls completely head-over-heels in love with her. When Blandy shows romantic interest in Grim, Billy is struck with mad jealousy and wants Grim out of the picture. Mandy consults Grim's encyclopaedia of monsters and realizes Blandy is actually a creature from another dimension. Despite Blandy showing her true form and leaving, Billy remains madly romantically infatuated with her; but only up until the following episode.
