Rudy's terraced dance-battle gym on Trovita Island — third stop on the Orange League circuit, awarding the Spike Shell Badge.
Trovita's challenge is a three-tier ladder battle with Rudy's Electabuzz, Starmie, and Exeggutor — one on each terrace — each Pokémon trained to move in synchronized dance with Rudy. The challenger must win all three to earn the Spike Shell Badge.
A hillside of three terraced arenas climbing Trovita's central slope, each terrace a wooden dance floor with a different Pokémon and a different battle matchup waiting. Colored flags mark each tier; Rudy's estate crowns the summit.
