Angry Bird creators said, "We threw it together so quickly no one thought about the obvious Muppet reference."
Angry Birds are attempting to be the 21 century answer to Mickey Mouse, with tons of merchandise already for sell at Wal-Marts and Targets throughout the southern US.
They plan to have a theme park open by 2013 and a feature length film out the same year.
The Muppets now owned by Disney hope the keep the Birds from branching out.
Once marketing indicated that their brand started to slip Angry Birds released a new game set in space that NASA helped design.
Due to the recent cuts in the NASA budget many scientist have had extra time on their hands and became fans of the game while waiting around until the astronauts came back from space.
Some scientist pretended to have been busy actually working while others boastfully announced that they figured out how to use the boomerang bird to shoot it in the opposite direction in order to crush the pigs nearest to the slingshot.
Critics were given the opportunity to use the new app and found it to be game like the other versions and agreed that it would once again give them something to do on the toilet while their legs went to sleep.
The game became a hit when parents downloaded the app on their phones and allowed children to play it so that husbands and wives could have a decent conversation while at a restaurant. Parents also began beating the more difficult levels for their children during bathroom breaks.
Now Birds has crossed over from the small screen cyber icons into soft squeezable toys. The overpriced stuffed Angry Birds are instantly loved by children then just as instantly left out and forgotten until the dog has ripped out all the stuffing. Children then sob until a new stuffed bird is purchased and cycle repeats.
The second time around is less dramatic because studies have shown that kids only really like the big fat bird and all that is left for the second purchase is the yellow bird which none of the children really care about.
Angry Birds Creators are asking for anyone to please purchase the pay version of the new game as well as delete and repurchase the original so that they will have enough money to settle out of court with the Muppets.
