Roll out for three exciting Bubble Guppies episodes about trucks and jobs! First, the Bubble Guppies learn all about different kinds of trucks on their way to the Big Truck Show to see the one truck that can turn into a giant robot - Humunga-Truck! Awesome! Then, when Oona’s friend Avi breaks a bone in his tail, he needs a Clambulance to take him to the hospital. The Bubble Guppies then learn that it’s a doctor’s job to make everyone feel better. And then, when a fire-breathing dragon threatens to burn down the Bubble Guppies’ royal kingdom, it’s Firefighter Gil to the rescue! But he doesn’t have just a fire truck – he has a water-breathing dragon!
