Gyftrot is a species of monster encountered in Snowdin Forest. It is later found as an NPC in outside the Mysterious Door cave.

Gyftrot appears to have the body of a reindeer with noticeable differences. It has a mouth that opens sideways which contain a bunch of pointy teeth. Its antlers branch in three different directions, two of them pointing up having pine trees on top of them. Other basic details are the four polka dots on its back, and the variety of decorations it has on it, such as a cup, a picture frame, streamers, etc. The protagonist can add more to Gyftrot, like googly eyes and such.
