Pokédex entries

What each game says about it, in the games' own words.

Black / Y / Alpha Sapphire	It lures prey close by dancing and waving its arm caps, which resemble Poké Balls, in a swaying motion.
White / X / Omega Ruby	They show off their Poké Ball caps to lure prey, but very few Pokémon are fooled by this.
Black 2 / White 2	It moves the caps on both arms and does a dance to lure prey. It prefers damp places.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
