From Bulbapedia, the community-driven Pokémon encyclopedia.
Pokémon Quiz (Japanese: ポケモン クイズ Pokémon Quiz) is a question-segment that it's only exclusive in Japanese version of XY series, while the dub this still features Who's That Pokémon? segment.
Pokémon Quiz follows a simple concept. The silhouette of Pokémon is revealed, then other four silhouettes appear alongside it: one being identical to the first silhouette, two being that of similar Pokémon species and one of them being that of Team Rocket. The viewers have to remember where the correct silhouette was, which is revealed alongside the actual Pokémon species after the commercial break.
