The bug occurs when you click the “C” button

You walk up to the water and press the ‘C’ button, and the dinosaur starts to shake, gets wet and then suddenly dries off. My friends and I discovered this glitch by chance; three other people from our group tested it and it worked for all of them. You can see everything clearly in the video.

I saw the dinosaur start twitching strangely, and there was an animation showing it getting wet and then drying off

In theory, when you press the letter "C," the dinosaur is supposed to crouch, but what actually happened is what I described and what the video shows
