After an accident, the heroes discover some ruins. Team Rocket goes inside and find a relic, but this causes a giant Gengar to appear, which absorbs everything. A relic the heroes found at the ruins summons an Alakazam, who fights Gengar, but the legend says that these forces will destroy everything. To soothe them, Jigglypuff sings a song, but this has no effect, except that a third giant is summoned to solve the conflict...
