While at Grandma and Grandpa's house, Caillou looks for a special hiding place. Grandpa shows Caillou the special place his Daddy used to hide in when he was Caillou's age. Caillou is very excited about the neighborhood rummage sale until he's asked to figure out what he'd like to contribute. He's not so sure he wants to part with any of his toys. But in the end he's pretty happy with the new stuff he comes home with. When Caillou's brand new T-shirt is ruined by grape juice Grandma diverts disaster by recycling it and turning into a one-of-a-kind shirt that is tie-dyed with grape-juice star bursts. Caillou helps Mommy clean out the attic when they come across an old chest, and discover neat treasures inside. Caillou and Mom go to the library for story time. Caillou has scribbled on one of the books he borrowed, and is afraid to bring it back. Clementine's Mom who is in charge of story time cleans the book. Caillou takes home a new book and this time, he will be extra careful with it.
