Looking in the far desert feels like...ARGGGGGGGH?

So...I'm on a little mission. Viv sent me out to see if I can catch Trapinch.
The chances are kind of low (2%?) So it'll be hard especially since I couldn't  catch
Ditto.... I'm going be doing my best cuz I'm also looking for a Vibrava out there.
Route 225! I'm coming for ya~!
