Forget the squirrels. This time, it's a monkey. With personal boundary and hygiene issues. OK, it's a squirrel monkey. A lousy, stinking, rude squirrel monkey.
Pirate treasure? A top secret mission? A terribly rude monkey with personal boundary and hygiene issues? Two out of three of those things sound like a dream come true to the young, clumsy, and terribly unscientific Waldo “W.B.” Baron, when his clever inventor parents are hired to go on a secret treasure hunt. The Baron family dives into adventure with their steam-powered submarine, but they aren’t prepared for the complications that occur during their trip, which include shark attacks, deep sea diving mishaps, and even a pirate’s curse, all of which W.B. is lucky enough to discover, one stumble, trip, and fall at a time.
