Young Ava is very excited to see Nana Dot (who's rather short-sighted). Nan's fun! And she's funny! And if that's not enough, can Ava's mad Nana see Squishy McFluff? Ava and Squishy are up to their normal no-good when Dad whisks them off to Nana Dot's - Mum's got to go to the hospital to bring back Ava a baby sister! But mad Nana Dot's lost her glasses so can't see Squishy McFluff ... and a trip to the hairdresser's, the post office and the fishmonger all end in adorable disaster.
