Paul the Plumber to the Rescue!

It's a sunny morning, and Bobo has a problem: the toilet won't flush, and his favorite toy, a tiny orange-suited diver panda named Umbe, is nowhere to be found. Papa Wang rolls up his sleeves and tries the old plunger, but the clog holds its ground.

When Bobo wants to reach in and grab it, Papa gently says no: that job is for plumbers, with training and care. Beep-beep! Paul the Plumber arrives in his blue van, makes Bobo his official Flashlight Helper, and sets one big rule: no paws in the toilet.

With plungers, friendly fizz, and a twisty drain snake that only a pro may turn, Paul goes to work while Bobo shines the light. What's hiding down that pipe? You'll have to read along to find out!
