The mascot of the Predators is Gnash, a blue saber-toothed cat. Introduced in 1998, Gnash's trademark includes stunts, such as very fast rappels, zip lines, and a pendulum swing that takes him under the scoreboard and just inches off the ice. To go along with the saber-toothed cat mascot, Predators fans proudly use their Fang Fingers during each power play of the game. There are foam saber-fang gloves that can be purchased, but most fans simply curl their index and middle fingers on each hand into fang shapes and brandish them in an up-and-down motion. Fang Fingers are done to the horror sounds from the Alfred Hitchcock movie, Psycho.
