The company first revealed plans for the new parks in December. "We will be developing a service which brings together the digital world and the physical world in a way that's never been seen before," it said at the time. "The popularity of Angry Birds isn't restricted to any age, sex or social group, and the activity parks too will be designed to be interesting places for absolutely everyone, all around the world."

The play parks will include Angry Birds-themed animal spring riders, swings, sandpits, climbing towers with slides, as well as a new Angry Birds arcade game. The promotional video (below), which offers a better idea of what the final parks will look like, even features an Angry Birds Cafe.

"Our goal is to motivate the fans, both adults and children, to exercise and enjoy the outdoors," said Harri Koponen, Rovio's executive vice president of licensing and merchandising. "Sarkanniemi theme park, in cooperation with playground manufacturer Lappset, offer a delightful Angry Birds experience for the whole family."

According to Lappset, one interactive element of the parks will involve GPS functionality. When you enter the parks you'll get location-based Angry Birds levels on your mobile phone that you can also play in other locations. The first look the public get at the real world offshoot of the game will be at Finland's Sarkanniemi Adventure Park, on April 28.
