The Rio Caged Birds should be in Angry Birds 2 as extra birds. They could have somewhat unique abilities. I will now list the potential abilities for all six Birds. Rick, The Yellow Caged Bird, his ability could be like Laser Chuck from Angry Birds Space. Where you tap the screen and Rick will Dash into the direction where you pointed. Billy the Purple Caged Bird, Billy's ability is spitting out fried chicken bones. He can spit out 3 bones at a time. However the bones are very durable and they break easily. John, The Green Caged Bird, John's special ability is him turning into a ferocious monster. Tap on the screen and John will transform into his monster form, and he will obliterate anything that's in his path. Brick, The Blue Caged Bird, Brick's ability is literally just Blu's ability from Angry Birds Rio. Where he will flap his wings if you tap the screen or if he touches something. Kyle, The Red Caged Bird, Kyle's ability is similar to Han Solo from Angry Birds Star Wars, where he takes out a laser blaster and shoots three times. Dane, The Pink Caged Bird, Dane's special ability is using his freeze ray. Tap the screen and Dane will use his freeze ray, which would be able to freeze blocks and pigs. Please add them to one or both games Mr. Angry Bird, I'm begging you! Also to add attention to detail, when the player uses Brick, make sure he has a scared expression instead of an angry one. Because Brick is kind of scared of almost everything.
