Series 5: 11. Cub
Alphablock L tells a story about how Alphablock U is unhappy in the forest with nothing to do until a fox CUB appears. It has lost its mum, and U is determined to help the cub find her. They reach a wide river and manage to cross it in a TUB. They shelter from the rain in a HUT. The sun comes out, but there is still no sign of the cub’s mum. A BUG appears, and they all fly to the last place it saw her. However, there is no sign of her until Alphablock M appears. Then, from behind some bushes, MUM steps out. U couldn’t be happier.
