The older two had a grand time playing on the playground equipment.
They played on the alligator-crocodile-dragon-thing.
They traveled through wormholes. At least, that's what this cylinder always makes me think of. Because all wormholes are made of energy and green metal mesh.
They rode on the green reptile again.
They helped Daddy set up his equipment and tell his interns what to do.
As is so often the case, I'm left wondering: Why didn't we do this more often?
