Alphablocks A and M take a parcel to Alphablocks T, P and S - the Trusty Postal Service. They try to make a postage STAMP for it. A large boot stamps the parcel flat! Alphablock S has to reinflate it. They try the STAMP again - success! Next, Alphablock I wants T, P and S to deliver an elephant to its home. But how? It is very heavy. They try to make it SPRINT, but it runs amok. It won't SPRING home, either. They make Alphablock P STRONG so that she can carry the elephant all the way home on her own. 

The Alphablocks panic when a SNAIL appears in their vegetable garden and starts to CHOMP its way through the vegetables. In a FLASH, the snail gets larger and faster. They follow its TRAIL and realise that it is only attracted to green vegetables. They make a special GREEN patch to distract the snail. Now, the Alphablocks can enjoy a vegetable feast in peace.
