Dawn

 * Tumblekit is one of Dawnflower's three kits. He travels through the Great Journey with the rest of the Clans.

Twilight

 * It is revealed that his sister, Minnowkit, persuaded her siblings to explore the RiverClan territory, and they came across a bad-smelling puddle. Minnowkit dared her brothers to drink some before also lapping some up herself.

As a result, this caused the kits to become violently ill. when their mother, Dawnflower, washed them, she also licked some of the liquid and became the first fully-grown cat to fall sick. Eventually, Tumblekit dies from the poisoning, although the other RiverClan cats recover.
