Cut to Caillou in his room, playing with some toy cars.
Caillou: Vroom, vroom, vroom, vroom!

Caillou walks down the stairs and into the living room. He doesn't see anybody.
Boris+Doris+Rosie: Surprise! Happy Birthday, Caillou!
Caillou: Wow! Thanks mommy, daddy, and Rosie.
His parents and Rosie look upset.
Cut to the kitchen.

Caillou blows the candles.
Later on, when Caillou slices the cake, some water splashes at him. It is revealed that the cake was just a water balloon.
Caillou: What was that?!

Caillou: I hate bạn mommy, daddy, and Rosie! You've ruined my birthday!
Caillou cries and runs to his room.
