When Madame au Lait is called away to give Chikidee her ping pong lesson, Tommy and Tallulah bake a massive sticky carroty cake on their own. Ignoring the recipe, they make so much mixture that the oven explodes when they try to cook it, showering the whole town with sticky gunk and bringing Pufferty to a standstill. The race is on to free him before Chime Time.

Tommy and Tallulah are having fun helping their friends but do not stop first to ask what their friends need. So Lopsiloo finds herself on the wrong side of the bridge, the wrong goods are served in Battersby's shop, and Pufferty's favourite ball gets thrown out when they tidy his kennel. The twins only realise the error of their ways when they take McCoggins scooter away for cleaning.

Madame Au Lait is cleaning the clockhouse, so Tommy and Tallulah take their jammy sandwiches to their room to eat. When some jam gets splodged on a blanket, they clean it themselves to avoid upsetting Madame Au Lait, but it floats off and lands in a muddy puddle when they hang it out to dry on Pufferty.

Chikidee is making slow but steady progress learning to fly, so Tommy and Tallulah make a gigantic paper aeroplane to help without realising that Chikidee cannot control it and has no idea how to land.

Tommy and Tallulah offer to do the polishing so that Madame Au Lait can make their favourite fruity trifle. While she is out buying the ingredients, the twins go polish crazy, thinking that the more they use, the happier Madame Au Lait will be and the more trifle she will make. The clockhouse is gleaming when Madame Au Lait returns, but when she sets a hoof on the floor, she finds that it is as slippery as an ice rink.

The twins are asked to collect McCoggins' bell for a town performance, but Tommy and Tallulah manage to break it despite Battersby's warning that the clapper is fragile and does not have a spare. Deciding they must make a replacement, they look everywhere for something to use and try some very unusual options to get the bell ready for Chime Time.
