GameStop Press Release

CELEBI CHARACTER DISTRIBUTION OFFERS CHANCE TO CATCH NEW POKÉMON IN POKÉMON BLACK VERSION AND POKÉMON WHITE VERSION

Get a Mythical Pokémon Celebi Not Found in Normal Gameplay at GameStop Stores Nationwide

BELLEVUE, WA-February 16, 2011 - Don't let the limited chance to catch the Time Travel Pokémon Celebi pass you by! Beginning February 21, and through March 6, Pokémon fans can visit any U.S. GameStop store to receive the Mythical Pokémon Celebi through a character distribution event for their English-language copy of the Pokémon Diamond, Pearl, Platinum, HeartGold, or SoulSilver Version games for the Nintendo DS family of systems. Not found in normal gameplay, this special Celebi also has a move that it cannot get through normal training called Nasty Plot, which greatly increases Celebi's Special Attack stat.

This exciting distribution from The Pokémon Company International and Nintendo comes just weeks before the North American launch of the Pokémon Black Version and Pokémon White Version video games. Receiving the special Celebi character distribution will give players the opportunity to catch the Tricky Fox Pokémon Zorua in Pokémon Black Version or Pokémon White Version when Celebi is transferred into the game. Players will not be able to meet and catch Zorua any other way in the games! Zorua recently made its debut in the full-length movie Pokémon: Zoroark-Master of Illusions on Cartoon Network. Fans can also catch a free screening of the movie at participating theaters on the Pokémon Black Version & White Version Tour!

Details for receiving the Mythical Pokémon Celebi:
What: Special Celebi character distribution
Where: GameStop stores nationwide
When: February 21-March 6
How: Players must have a Nintendo DS, Nintendo DSi or Nintendo DSi XL system and their own English-language copy of Pokémon Diamond, Pearl, Platinum, HeartGold, or SoulSilver Version video games (each sold separately).
Notes: Players must have acquired the Pokédex within their game. Players must have no more than two Wonder Cards in their possession.
