Great looking game. I know it is a demo, but I have a random beldum showing up in a Pokeball near my starter. I chose Mudkip and then right near Birches first note after the Team Magma fight there is a Beldum there. I then proceeded to the grass for random encounters and Mudkip will not appear. The wild Pokémon was there. I cannot get past that point. What am I doing wrong?
