Caillou talks about both his Grandpa and his Mommy at the end of the show.
Caillou once again hosts a matching card game at the end of the episode. First, the game is played with three spaceship cards and three astronaut cards. It's then played with the three sets of two dinosaurs of the same color.
Caillou sings a song called "Let's Go to the Museum" in-between the second and third stories.
Caillou: Ms. Martin, are there any bears on other planets?
Ms. Martin: I don't know, Caillou. That's a very good question. Maybe there are bears on a planet far far away somewhere.
Rosie: Ooh, elephant.
Daddy: That's a woolly mammoth.
Caillou: He needs a haircut. Is he really an elephant?
Daddy: He's the great-great grandfather of all of the elephants.
Caillou: (regarding magnets) They can stick upside-down. I wish I could do that.
Narrator: Caillou was learning all about magnets, but he was going to need a lot more magnets to play with. He stuck magnets on the stove, on the toaster and on the big spoon.
Mommy: I think we have a magnet fiend on the loose.
Mommy: Did you know that magnets stick to lots of things?
Narrator: Caillou wanted to see what else magnets could stick to.
