After building a robot friend for Ruari out of cardboard at the playschool, the children feel like making things out of clay like you find at Otter creek. At the creek they get a little help from Orin the Otter, who sings them a little tune about finding the best clay to sculpt with, not too hard and not too soft. The children get to work, but they still aren’t happy with their models. Glammie Guppie turns up and reminds them what they have to do to get them just right.
