You attempt to flee!
There is no escape!

The Feraligatr then chomps the skull of the tiny pokemon trainer, foolish enough to go out into the tall grass without a pokemon for protection. I mean, the kid even tried to throw a Poke Ball at it. Full health. Stupid.

This is a cautionary tale to all 10 year olds who think they can just up and leave their hometown without talking to a professor first. THIS is why we put a sign at the gate! DANGER! Wild pokemon live in tall grass! Inform your kids.
