On a hot summer day, you and your best friend decided to go swim at a river near by. As you two are on your way, you catch a glimpse of a large, scaly head.. then another one after that. You poke your friend, who's on their phone, and point into the distance. You explain what you saw, and they just look at you confused...

Eventually, you two make to the river. You slip your clothes off, now just in your swimsuit; and so does your friend. After about an half-an-hour of splashing each other and such in the water, your friend decides to leave momentarily to use the bathroom. They leave, going to your house quick. Now you're just standing in the water, chilling there.. Until you were startled by a sudden loud stomping behind you...

You turn around, only to see a huge five-headed, mainly brown, dragon thing standing walking back with pounds of dead sea life in its mouths. One of the heads look straight at you, tilting it's head slightly while the other heads of the Hydra just eat the dead fish. The 5th Hydra head seems to take great interest in you... What do you do in response..?
