Alphablock H has built a henhouse and needs a HEN to live in it. She and her friends end up making three hens and decide to give them names. The pen shows them capital letters, and Alphablock C explains that they need them for names. They name their hens PEN, JEN and ZEN. The hens love their name badges. Then, C introduces a parade of animals with different names, each one wearing a badge - CAM the ram, PAT the cat and ZAK the yak. There's just one more name to be given - BEN the pen!
