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.

'In Alphaland, there was a farm, A, E, I, O, U', sing the Alphablock vowels. But N complains that there are no animals on their farm. When a JET appears, he protests that it is not an animal. Then a cow parachutes out. To N's astonishment, a ZIP, a bubble that goes POP and a pool of MUD produce two hens, a sheep and a pig. The animals turn out to be divas and threaten to take over the chorus of the song, but N doesn't mind. He's delighted to have a proper farm at last.
