Frosty was the name of Kootra's rock during his playthrough of Rock of Ages with Ze. Kootra switched to Frosty towards the end of episode 3 of his playthrough and used it continuously since. Even though Frosty is just a big snowball with a face, he has won various battles against Ze in during the series.
It is not known how long Kootra will use Frosty against Ze.
- Frosty's original name was "Snowman".
- The name Frosty most likely comes from "Frosty the Snowman".
- Even when he is burning, Frosty is immune to flames so he still stays as a snowball, and doesn't melt.
