Instructions:

Your mouse guides the Small Green Fish (I named her Shern). Help Shern eat smaller fish to get bigger. If you're big enough you can eat bigger fish. But beware: Fish bigger than you can eat you.

Also watch out for jelly fish. They kill you instantly.

Pufferfish (due to being spiky) requires a very big fish to eat. Also they can blow themselves up (I'm not changing this line. It's too funny).

Trash will fall from the ocean ceiling after a while. DON'T TOUCH IT.

Notes:

#TeamSeas. Um, Donate to Team Seas to stop plastic pollution. I put non plastic trash in because... I don't know. 

Forgot what else I was gonna put here.
