You do NOT want to get on this guy's bad side - especially if you're a stuffed imposter.

Or at least, that's the message found in this bizarre 15-second Instagram video of an iguana attacking what appears to be a stuffed lizard just about his size.

What makes it so captivating (and, possibly, a little disturbing) is that, until the attack, the iguana appears to be completely fine.

Then, he goes from zero to 100 and loses all chill, rapidly spinning in circles around the floor. This frenzy only lasts for a few seconds, before the iguana stops - and then gives the stuffed animal a gentle nuzzle.

Usually, aggression in male iguanas can be chalked up to one of two things: rampant hormones during breeding season or the activation of their defense mechanisms when placed into a stressful or uncomfortable situation. Alternatively, this might have simply been his idea of "playtime."

Either way, it didn't take him very long to kiss and make up with with his stuffed companion.

You have to see it to believe it. Check out the video for yourself below.
