Abney, Teal and Neep make mysterious noises on a misty day. They try to get Bop to join in the game but it's not so mysterious down by the lake.

It is a boiling hot day; much too hot to do anything apart from eat ice-cream and go swimming. But when Abney and Teal finally get to the lake there's something not quite right about it.

The Poc-Pocs have got hiccups. Teal finds the cure, but they are spreading! When they reach Bop something has to be done.
