You and your friends decided to go on the beach for your friends birthday and you guys go fishing first. You notice something or someone in the distance but decide to ignored it. Then the birthday boy decided thanked you again.

"Hey bro thanks for taking us here on the beach, it's the best present i had!"

You said it's no problem. You looked up again to the thing you see moments ago. It's gone, you think it swam right back in.
