Here’s a step‑by‑step guide for setting up and playing a Randomlocke challenge of Pokémon Black 2 (known in Spanish as Pokémon Negro 2) using a Spanish ROM.

Ruta 1 – Poochyena (Tritón) – Vivo
Ruta 2 – Wurmple (Mariposa) – Muerto (Gimnasio Veneno)
Ciudad Engobe – Huevo – Eevee (Sol) – Vivo

"Randomlocke" could be a specific ROM hack or a mod name. If it's a hack, I might want to explore its unique features. However, without more info, I should state that it's unclear and suggest researching reputable sources for details.
