Dates for European legendary beasts event
Pokemon Events — 15 January, 2011
Details on the European event for Raikou, Entei and Suicune have been released. Each one will be available over Nintendo WFC for a week in February. They are the same Pokemon currently available in USA/Canada - not only are they shiny, they also come with new moves they don't normally learn!
All three have Extremespeed. Raikou has Weather Ball and is available from February 7th-13th. Entei has Flare Blitz and is available from February 14th-20th. Suicune has Sheer Cold and is available from February 21st-27th.
They are available for all fourth-generation games, so if you have multiple games (e.g. Diamond and HeartGold) you should be able to get them multiple times! The process is the same as usual - simply go to Mystery Gift in the very first game menu, Receive Gift, then pick it up from the delivery man in the PokeMart.
