The Ninky Nonk is a funny kind of train, made up of a number of differently sized and shaped carriages.

The Tombliboos, the Pontipines, Upsy Daisy and Igglepiggle all have their own carriages, although they often travel in each other's.

The Ninky Nonk careens through hedges, clambers up and down trees, and even occasionally travels upside down along the branches of trees! All the toys must be sure to buckle themselves into their seats securely!

The lights on the inside and outside change colour when it is about to start moving, or come to a stop.
