Educational fun. Z has left the others in charge while he has a nap, but before long disaster strikes and Alphaland needs colouring in again. 

T has such a tip-top time making words with his friends that he invites S to join him - and soon wishes he hadn't. If only he could start the whole day over again! 

This episode has fun with the 'st' blend and the words top, tub, tag, stop, stub, stag, lost and best.
