As Dennis's fifth birthday nears, he has yet to grow his fangs and Drac worries that his grandson might not gain vampire powers. Noticing the potential dangers her son might face living in Transylvania, Mavis starts to consider moving to Johnny's hometown in Santa Cruz, California in order to give Dennis a more “normal” childhood, much to Drac's disapproval. Drac tells Johnny, who does not want to leave the hotel either, to bring Mavis to California to visit his parents, Mike and Linda, but to make sure to keep her distracted so that she will not move, leaving Drac to "babysit" Dennis. Convinced that Dennis is a "late fanger", Drac enlists his friends Frank, Wayne, Griffin, Murray, and Blobby to help train Dennis to become a monster, but every attempt that some of them try fails. Drac and the gang then go to Camp Winnepacaca, Drac's childhood summer camp, only to sneak away after Drac finds out that the camp has become much safer and child-friendly but Dennis suddenly hugged your leg, and when Dracula looked to see who his grandson Dennis was hugging but Dracula as soon as he saw you, he feel in love with you and felt a zing for you. His heart race went sky rocket as he froze when he looked at you.

"Eeny feeny fanny foonyah wah wah?" He said as he speaking love-struck gibberish and will be doing most of the time around you as he continued looking at you with his heart racing and his huge love-struck smile on his lips.
