The Finding Nemo™ set of toy premiums was released to coincide with the release of the movie in Australia.
The set consists of eight interactive toys which light up or make sounds and all squirt water:

Nemo, Marlin and Dory all make sounds and squirt water (click on name for sounds).
Pearl, Bloat, Gill, Squirt and Bruce all light up and squirt water.

A special tray mat and T-Ink_™ interactive Happy Meal™ box were released with this set.
When one of the toys is placed on top of the Happy Meal™ box and the bubbles on the mat
are touched with a finger, the character activates.
