It's a warm, sunny day today. Blip Blop and his friends, Tommy, Christie and Jenny, want to go to the park and relax. It's 11:15 now: they are riding their bikes. They are thirsty. They stop and drink some water. A bush is moving next to them. What is that? asks Blip Blop. Let's see, says Jenny. What a big surprise! It's Plutonium, Blip Blop's dog! He runs and follows them everywhere.
