Sula and Amma go round to Bing's house to watch the fireworks. Sula doesn't like the bangs so she is wearing her earmuffs but Bing thinks he is brave enough to watch the fireworks outside in the garden. Suddenly there is a huge bang and a super-loud rocket sends Bing racing back inside and under the kitchen table in shock. Flop makes Bing an unconventional pair of earmuffs of his own so that he can enjoy the fireworks without the bangs.

Bing plays with a new orange balloon but when he bounces on it too enthusiastically, it pops. Bing is sad to lose his new toy, so Flop helps him put the balloon fragments in the Bye Bye Box, a memory box where things too broken to be fixed but too special to throw away are kept.

Flop is pushing Bing on the swing in the park when Pando arrives and wants to have a go too. They agree to let each other have turns by counting up to ten, but when Pando has his turn he won't count properly. Bing gets so cross he runs in front of the swing and gets bumped.
