It's time for spook-tacular fun as everyone's favorite mischief-makers meet the hairy and scary Wolfman in this full-length Halloween feature! Join chipmunk brothers Alvin, Simon and Theodore and their gal pals, the Chipettes, as they zip from one hilarious adventure to the next. Alvin has monsters on his mind and is sure that their mysterious new neighbor is a werewolf, but the thrills and chills really begin when Theodore starts to act strangely, too. And if that weren't enough, the gang works on a school production of Dr. Jekyll and Mr. Hyde, but when Alvin's antics get him yanked from the play, can the show go on? You'll be howling with laughter—and just maybe at the moon, too—in this irresistible family favorite.
