Outer space is a happy place...except for the evil space monkeys! Halloween is ruined after Mr. Boggarty injures his foot just a few days before his favorite spooktacular holiday of the year. Grumpy, upset, and not in the mood to celebrate, Mr. Boggarty still asks Trix and her friends to stop by on Halloween night...but warns them not to come inside the house. Ignoring the ominous message, Trix and her friends step through the front door and...Ka-BOOSH! The rocket boosters ignite! Now they're in for one wild ride-in outer space! Come on up to the haunted house! A terrifying place filled with all kinds of tricks, traps, evil space monkeys, and a terrifying seven-foot-tall, six-armed monster that stalks through Mr. Boggarty's humongous, fun-filled house. Monsters? Traps? Evil space monkeys? What else could possibly go wrong?
