Igglepiggle, Upsy Daisy, Makka Pakka and the teeny tiny Pontipines all decide to go for a ride on the Ninky Nonk but the Tombliboos decide to ride in the Pinky Ponk instead. They watch from the window as the Ninky Nonk takes all their friends for a very bouncy ride-what a silly Ninky Nonk! The Tombliboos are pleased to be on the Pinky Ponk, but then the ponk alarm goes off. The Pinky Ponk ponks into a tree and then into the Gazebo several times-what a silly Pinky Ponk! After such a "ponky" ride, the Tombliboos decide to ride on the Ninky Nonk with all their friends after all.
