A group of tea pets-cute clay figurines that are good-luck charms for tea drinkers-embark on a magical animated adventure to find a fabled mystic.

Nathan is one of a line of little toy porcelain figures that change colours in contact with water. But for some reason, his colour does not change, even though he was made by the Toy Master himself. One day, Nathan meets Timebot, a little robot. He decides to join him on an adventure to find out why he cannot change colour, and how to recover his lost ability.
