It's a bucket and spade day. On the beach, Ebb & Flo play at marching and hide and seek with Bird. They explore a cave and play shadow games. A strange noise and shadow frightens Ebb, but it's only Bird having fun. Flo promises she'll never laugh at Ebb being scared again. Back along the beach, it's still a glorious bucket and spade day. Flo starts a marching game on the way home.
