Well, looks like I'm about to find another party member.
*buy a bottle of Rust-rid in Zozo and go through the pub, having some random encounters along the way*
*end up in Mount Zozo after going through the pub, walk around for a while until a random encounter with a ursine enemy starts*
*five seconds later*
What the *beep*!? It stole my money! O_O
*defeat it a few minutes later*
No one steals my money, capiche?
