As well as the Regigigas distribution - which you can use in Pokemon Platinum to obtain the other Regis - the 11th movie, 'Giratina and the Sky Warrior, Shaymin' will be shown alongside episodes from all 11 seasons of the Pokemon anime.
New trainers will be able to enroll in a Pokemon Academy that will teach them the ins and outs of the games (though, Lord knows to what level this will be), while experienced players of Diamond, Pearl and Platinum can challenge eachother in the Challenge Zone.
Younger fans can take advantage of the face painting, balloon modelling and the opportunity to have a photo taken with the Pokemon characters that will be roaming around the event.
Finally, visitors to the event will be in with a chance to win a Haven family holiday during March, April, May or June next year.
The event will be decorated under the theme of the Sinnoh region, and familliar characters and even locations will be present at the event.
The events kick off tomorrow at the Nottingham River Festival, with most of the other events also taking place during other such festivals and fetes going on across the summer.
