Creature is a popular emote of a dog, particularly a Mexican Hairless Dog, aka. a Xoloitzcuintle. The original creature (seen below) is owned by Anet Veltman, who has uploaded numerous videos of creature on her Instagram and TikTok pages.

This emoticon was popularized in various twitch spaces, perhaps most prominently in the Artifact section.
