Tumblekit is a tabby tom with a plump, round face.
In the New Prophecy arc
- Tumblekit is one of Dawnflower's kits, along with his brother, Pebblekit, and sister, Minnowkit, in RiverClan. He travels with the Clans to reach their new home by the lake.
- As the Clans race across the Thunderpath, Dawnflower calls to one of her kits, who is panicking and running straight towards a monster. Crowpaw lunges forward to grab the kit before racing back to safety. The family makes it, with Crowpaw and the kit in tow. Dawnflower rushes over and gratefully takes her kit as Squirrelpaw calls for Leafpaw to check up on the kits. The medicine cat apprentice sniffs the two kits, listening to their chests to check for any breathing problems. Leafpaw announces that although they are scared and tired, they will be okay. Willowkit says they are going to be fine as the monster was never going to get them. Dawnflower doesn't take much notice to this, and instead washes the mud off her her kits' faces.
- While crossing a Thunderpath, two RiverClan warriors help Dawnflower carry her kits. Later, Dawnflower suggests all the Clans sleep among each other when she stops Tumblekit from chasing after a woodlouse. In the mountains, an eagle tries to hunt some kits, but Brambleclaw sees this and herds Dawnflower and her kits to safety. Later with the Tribe, Cinderpelt checks on Tumblekit and his family after the eagle encounter. Tumblekit and the other kits are eager to meet the Tribe kits, and Dawnflower gives Tumblekit and his siblings permission to go with the others to venture around their temporary shelter.
