It's Halloween, and the five little monkeys are eager to trick-or-treat. With babysitter Lulu as the group's chaperone, the monkeys venture into the night and encounter several costumed friends. Mischief ensues as the trick-or-treaters swap outfits in a furtive masquerade. Playfully illustrated with a colorful parade of animals and disguises, it's a lighthearted Halloween farce.

Christelow's rambunctious monkeys are decked out in their costumes and ready to play an elaborate trick that may end up jeopardizing any treats they might receive. Mama makes sure her little ones are ready when Lulu the babysitter arrives to take them out on Halloween night. Their costumes: banana, alien, ghost, goblin and princess. "Don't lose the rascals!" Mama cautions. All goes well until one monkey decides to switch costumes with a friend. Now that monkey is a blue bunny instead of an alien. The other monkeys think this is "SO funny" and follow suit. Though Lulu notices, like all great babysitters, she does not spoil the fun--at first. But the look in her eye foreshadows a comeuppance for her young charges. Suddenly Lulu announces that it is time for the new banana, ghost, goblin, alien and princess to go. "We have to get home for a big Halloween treat!" Suddenly, the disguised monkeys worry that they are going to miss something special and quickly follow Lulu and their friends to the house. Crafty Lulu and wise Mama soon sort out the confusion, and the mischievous bunch is quickly forgiven as they sample some tricky treats of eyeball cookies and worm juice. Fans of the author's previous monkey titles will welcome this silly new tale, but adults wishing for a safety message warning against similar copycat antics will be disappointed.
