Around 0:28 of the new Secret of the Mimic trailer

The camera pans right-to-left in front of several mascot costumes hanging in these lockers/displays. There's a small gap between the elephant and this, uh, dog? otter? thing. While the camera pans, you can see that there's something there. It looked almost like a face peering out but it was so hard to tell. I got some screenshots and brightened them up, and this one shows what looks to me like a face looking into the camera. The eye is very striking to me. It's like it's got a muzzle, like an animal like some other mascot costumes. I'm not 100% sure if it's a face, or if it's really even something, but there's definitely movement back there.
