Glowing eyes in the forest

A couple of friends are camping in the forest. Suddenly one of them sees something glowing red. In some distance in the forest. Of course, he immediately told his friends. But they didn't believe him at first. But that should change pretty quickly.

After the men were attacked by whatever, all but one of them got into the boat. A few seconds later, the buddy who stayed behind appeared at the top of the cliff. The friends yell at him to jump and swim into the boat.
