You try and thrash your way through the grass that easily comes to your waist, but it's becoming increasingly difficult. You've been going at this for over an hour, and your entire back is soaked with sweat. It's also not helping that it's clear and warm out, making your black cloak a beacon for heat. You fall back onto the impossibly high grass, letting it cushion you.

A loud noise comes at you, just as you've caught your breath. Neville Longbottom comes through a break in the grass, pauses, says "Hi, Ron! I think you better run!" then continues past you as you glimpse a Manticore rushing through the same break Neville did.

Should you:
A.) Run for your life
or
B.) Fight the beast
