Caillou Goes Shopping - Caillou's crayons are all worn down or broken, so Mommy suggests a trip to the store for some new ones. Caillou helps Mommy remember what she needs to buy - he remembers the list of items by making a little song out of them. When they're done they run into Sarah, and Caillou helps her find all her back to school supplies. Caillou Goes Apple Picking - Caillou's playschool is on a special field trip to an apple orchard. The children really enjoy learning about apples and picking them too. Caillou imagines himself picking the biggest apple in the whole world. Afterwards they enjoy some fresh apple juice. By the time they get back on the bus to go home, Caillou and his friends are all ready for a little nap! Caillou's Hallowe'en Costume - Hallowe'en is coming and it's time to pick out a costume to wear. Soon Rosie has three costumes she wants to wear, but Caillou still hasn't decided on what he wants to be. And time is running out! Finally a piece of blue fake fur gives him a great idea - he'll be a blue monster! His parents help him fashion an odd but effective monster costume out of bits and pieces they find around the house. When Leo and Clementine arrive they agree that Caillou is a very scary-looking monster indeed!
