Snowtuft was a villian in Erin Hunter's Warriors book series.
Snowtuft is seen in the Dark Forest training when Spottedleaf and Jayfeather visit. He is in the middle of a battle training session with several other Dark Forest cats, monitored by Hawkfrost. Snowtuft is watching the training session with his eyes half closed until Hawkfrost calls Snowtuft to come foward. He creeps wariy towards Hawkfrost as he calls him, and Hawkfrost asks if he is ready to learn. Snowtuft replies yes and that is why he is there. Hawkfrost calls Shredtail to come over as well. When he comes Hawkfrost grabs Snowtuft and throughs him in the air, exposing his belly, and Shredtail is ordered to tear it open. While Spottedleaf and Jayfeather leave in horror they can hear Snowtuft howling in agony.
Hawkfrost introduces Snowtuft to Ivypaw, a ThunderClan apprentice and one of the Dark Forest's visiters, under the mentor of Hawkfrost.
