Scrambler is playing with the Sunflower Valley children; Sunny, Saffron, Carlo and Cassia in the playground. It's the last day before they have to go back to school in Bobsville and they are all sad to be leaving. Scrambler gets a call from Wendy to help in the new yard. His job for the day is to play with the children and keep them away from the yard because Bob and the team are building a surprise. They are constructing a Baby Dome and need different materials to build it. There never seems to be quite enough of any thing... because Scrambler keeps making games out of the materials. First he makes Earth castles, and then uses the sacks for sack races, then mounds of sand for a sand castle town. Wendy, Bob and Ela get on with building the Dome walls, but they soon run out of mixture - Scrambler has taken all the sand! If they don't get the sand back the whole building will have to be taken apart and re-built. Ela introduces herself to the children. She has a new game for them.
