Auntie Ellie is a large sheep. She loves lying down by the river, watching over the lambs as they play. On a hot June day, while Stan and Little Red Tractor are haymaking, Auntie Ellie goes into the river to cool off and gets stuck in the mud! Auntie Ellie is much too heavy for Stan to lift, so he has to use Little Red Tractor to take the strain.
