An evil genius threatens Christmas. His name is Twinkles. Furry and full of himself, Twinkles the cat takes self-interest to a new level. Not a huge problem...until he disappears, turns himself into a human, and maybe kills a few of Santa's reindeer. Star and Ben never dreamed that cat-sitting could be this difficult. But things only get worse as more (reindeer) bodies start piling up. Using his newly discovered opposable thumbs, Twinkles phones his pet-sitters. His claim? He's innocent. He'll do anything if Ben and Star will clear his name and save Christmas, even (shudder) cuddle. Join Star and Ben as they return Twinkles to his former fluffy body and find the real murderer in this humorous holiday tale of magical intrigue.
