Big and Small want to build a waterslide in the pond. They know the pond is the frogs' home and ask permission first. However, Big and Small don't speak frog and think the frogs are saying yes when, actually, they are not happy about the waterslide at all. Big and Small give up on the idea although Big has another idea. He builds a slide in the garden for Small, with a cushion for Small to bounce onto at the bottom. And the frogs are happy too!
