A big sand castle

Randy, ChaCha and Catherine go to the beach to have some fun, and here they meet Tau and his father, Mr.Dinton. Mr.Dinton is an architect and he moved to Greenhill Town to break down an old boathouse and build an Orgel House instead. Strangely, though, ChaCha notices a shovel car that doesn't seem to be working properly. At night, Randy and ChaCha go to see the shovel car and they find out that it is actually a circus elephant, Cindy the elephant shovel car. Cindy tells them that she is sick and tired of continuously breaking houses and buildings. And so they all decide to make the biggest sand castle on the beach, which surprises the people of the entire town. And Cindy learns that in order to make something new and nice, some old things have to be destroyed.
