Caillou is excited to get up out of bed because today is Mother's Day and he's got a special gift for his Mom. He goes downstairs and wonders where Mommy is. Daddy explains that he let her sleep in and he's making her breakfast. They take the breakfast up to her and Caillou wishes her a happy birthday. Mommy tells him that it's not her birthday, it's Mother's Day. Caillou wants to give her the present, but Daddy suggests that he give it to her when they go to brunch. Since it's a special day, they're going to brunch (breakfast / lunch) at a restaurant. At the restaurant, Caillou and Rosie press their faces against a fishtank and then are escorted to the table by a waiter who calls them sir/madam. Caillou likes this. At the table, there's no food and Caillou learns that it's a buffet, so you have to go get the food. He's eager to get the food, but learns that you have to take your place in line. He wants to carry his own plate, but when he ends up sneezing and blowing away some of his food onto the floor, Mommy ends up carrying it for him. Caillou loses his appetite, but it perks up when the dessert tray is brought out. He asks if Mommy is going to get a cake with candles and is told that they don't usually do that for Mother's Day. The waiter, however, decides to be accommodating and brings a cake with candles. Caillou helps Mommy blow them out as he wishes her a happy birthday, or rather a happy Mother's Day and he also gives her his gift, one of his toy cars. (thetvdb.com)
