Greenland is the first episode in Angry Birds World Tour (new version).
King Pig woke up one day and decided he wanted to try to take over the world. So, he went to the North American island Greenland. There he set up a base camp with an escape rocket. When the Birds found out, they went to Greenland too......
King Pig has been defeated, right? WRONG! Badly injured, he gets into his escape rocket and flies away to Canada. The Birds have implanted a slingshot in the ground and are prepared to go after him when they see a note: "If you want to come after me, don't hesitate. I went to the home of the hockey teams you hate." It turns out that the Birds hate the Canadian hockey teams in the NHL.
