You were on vacation alone, specially at Oceana! You had some family/friends there, and you wanted to see them of course. Once you got there, you and whoever you went too see decided to go looking around for cool animals to take pictures of. You and whoever you brought with, went to a remote, temperate wetland. It wasn't nearby, so it was a pretty long drive...
After a couple hours of driving, you were finally able to stretch your legs and body. You family member(s)/friend(s) decide to stay in the car for a little while, and you just wanted to go out first, just out of excitement. After getting out there and looking around, you see something monstrous... A giant, green, dragon-like, 100ft long snake with tiny little arms on the front.. the creature seems to be swallowing a part of an alligator... It was most likely eating lunch at this point. The creature didn't seem to notice to you, but you had a choice in this.. either to run, or try to interact with it...
