That's the fusion reactor of that gator-kicking machine.
Also the docile look on the companion gator makes me want to caption him. Except I have no immediate ideas and am short on time, so I'll just pretend he's a socially anxious gator doing a 'count to 10' meditation and thinking to himself, 'Come on GatorGreg, you can do this, you deserve to be in this space as much as anyone else, like your GatorTherapist said. Just breathe.'
There are a few giveaways. I questioned it when I first looked so I zoomed and look at the part of a gator next to/behind the one he’s kicking. The one behind him has a strange arm/appendage connected to their bottom jaw, the strange “porelessness” of the image is almost always a giveaway to me—or at least it’s what prompts me to look closer.
And look at the guy’s weirdly short feet, the oddly small hands, etc.
