3 months average. It depends on how often you use it.
Yes, if you buy it, you can use it over and over, but you have to wait an hour after each use.
You go to the regular Angry Birds app. If you start a level you can't beat you press the gray eye that is beside the Pause button and agree to pay 99 cents for the Mighty Eagle. Once you press the grey button, a can of sardines lands on the slingshot. Sling that can at the Pigs' structure. This summons the Mighty Eagle. The Mighty Eagle can only be used once an hour if the level it was last used on was not completed normally. If the last level the Mighty Eagle was used on was completed normally, you don't have to wait to use it again (just to be clear, you only purchase the bird once you just can't use him more than once if you didn't complete a level normally).
You don't get the last bird.
in your bum
Don't follow what that last guy said. To get the Mighty Eagle, you must get him through an in-game download. If iPhone/iPod Touch, buy some iTunes points, and make the purchase. If a different device, get the necessary money. When you've purchased him, you may use him. He can only be used once an hour, however, if you've completed a level, you may use him however may times you please. When you've downloaded it, a can of sardines should be in one of the levels (I'm serious about the sardines, trust me.). When you drop them on the building, the Mighty Eagle bird will drop down and destroy everything in the area (not guaranteed). If used to solve a level, you won't get points.
The last episode of Angry Birds Rio called Jet Battle comes out in November 2011. Sorry if there is no exact day it comes out.
Currently the Beach Volley Update.
Behold, Jet Battle, the 6th and final episode of Angry Birds Rio. However, it's not done yet.
In two years
As of my last update in October 2023, there isn't a specific "new" Angry Birds Seasons game, as the original Angry Birds Seasons was released in 2010 and has had multiple updates over the years. However, the series has seen various iterations and seasonal updates. For the latest information on any new releases or updates, it's best to check the official Angry Birds website or their social media channels.
As of my last update in October 2023, there has been no official announcement regarding the release of Angry Birds Space on Roku. For the most accurate and current information, it's best to check the official Roku channel store or the Angry Birds website. Keep an eye on gaming news outlets for any future updates on this title.
