Pokémon Ruby - Gotta Catch 'Em All!

Ash is catching Pokémon in a world consisting of an infinite two-dimensional grid of houses. In each house there is exactly 1 Pokémon.

Ash starts by catching the Pokémon that are in the house where he starts. Then, he moves to the house immediately North (N), South (S), East (E) or West (O/W) from where he is and catches the Pokémon that is there, and so on.

Attention: if he passes a house where he has already passed (and, therefore, where he has already caught a Pokémon), there is no longer a Pokémon there for him to catch!
