Summary Rudi and Trudi are flying through the skies and feeling the heat when Rudi decides to take them for a little dip. The pair suddenly find themselves sitting on top of two fountains which stop abruptly and they are dropped inside a huge smelly chamber which they realise is the inside of a whale, called Winston. Quickly Trudi spots Winston's blow holes and Rudi comes up with a plan to escape. Unfortunately it doesn't work and the pair are trapped. Each time they try to escape a wave knocks them both over. Finally they make it to the whale's mouth but they another wave knocks them back to where they started. They make a final failed bid for freedom and they end up trapped in a net and a shell respectively. At the point where they are about to give up hope they discover "Whale Belly City" populated by Lobsters, a Turtle and a Walrus and a tug boat Just as they are getting to know their new friends, Winston comes to a halt and the animals realise that the whale has beached. Now that Winston isn't underwater anymore, Rudi and Trudi are able to get out through the blow holes. They persuade Winston to open his mouth and all the other animals sail out on the tug boat Between them they attach a huge chain and try to drag Winston out to sea but he's too heavy. Rudi comes up with a plan to save the day. He gets hold of a megaphone and makes funny noises through it. It turns out that he is talking whale and suddenly two whales appear to give them some extra power to drag Winston out to sea and back to safety. All of the animals are glad to be back on the outside again and the whale is happy to be back in the water.
