Today Little Hippo is playing firefighter. But as Firefighter Hippo pedals his fire truck through the jungle, he gets trapped in a mud hole, tangled in tall grass, and stuck on a hill. That's nothing compared to the biggest surprise of all-a real fire. It's a good thing the little firefighter knows exactly what to do!
