@above: Simple. Glitches.
And yeah, DarkDoom, even though the left side of Brevis Town leads to Mt Sitor, the right side leads to Resta Cave
EDIT: If you fish at a fishing spot while on a bike, after the battle/message, you start walking really fast as if you were on a bike until you "dismount" or move to another map. Simple sprite problem. (If you don't get it, see attached pics. Don't mind the graphic changes, I'm not on my reg comp... REALLY sorry, DarkDoom, for editing the sprites in the first place )
Oh, at while I'm here,
Not even a nibble...
"Theres something on the line!"
There's something on the line!
EDIT2: Also, you can't run from fished pokemon
