Splasher, an amphibious vehicle, arrives into town for his first day of work taking the hotel guests for sight-seeing tours by land and sea. After a brave water rescue, he becomes known as Super-Splasher. Determined to live up to his new superhero name, he interrupts one of his tours to rescue some people who don't need rescuing! Will Splasher ever put his superhero skills to use again? It's a hot day in Sunflower Valley and Bob and the team are going to surprise Gripper and Grabber, who are coming from the city, with a new shelter. But that's not all. The shelter is also for Bristle, Flex and Tumbler! The team have to finish the shelter in the heat before Gripper and Grabber arrive. Bristle is eager to lend a hand but ends up hindering rather than helping. That is, until Bob needs someone to slow Gripper and Grabber down so they can finish the shelter in time.
