When Toad finds himself with a case of puddle hiccups, it's up to Yukee and the rest of the garden gang to find a cure.

It's been raining, and Toad is resisting the urge to join in with Yukee and her friends' game of musical mud-squelching. However, he can't resist the muddy beat and is soon squelching with his friends.

Yukee is desperate to meet the worms that live in the soil beneath the garden. Learning that they only come out when it rains, Yukee tries to simulate the sound before realising that it's the rhythm that the worms really love.

As everyone huddles in Sonny's caravan during a storm, Toad admits he's frightened of the sound. Yukee must find a way to use the pitter-patter sound of the rain to help calm him down.

Sonny thinks he has found a box of broken junk, but it actually contains the parts of something very special. Yukee and her friends must work as a group to put all the pieces back together again.

Everyone is bringing presents to the opening of Twinkle's zen garden, and Yukee wants to take something too. But when she can't find anything, they encourage her to sing about her frustration.
