Angry Birds RiOa is a sequel of sorts to Angry Birds Rio, but more like AB Space with the gameplay. It is created by Rovio, Fox Digital Entertainment, Blue Sky Studios,and WB Games. It is based of AB and the MAD sketch.
Nigel (well, a AU version) is guarding a AU Jewel in a cage. Then Blu sees a shooting star, discovers Abin Sur, gets the ring, pretty much the entire first half of the sketch. At our world, The Birds are getting their eggs cooled down, as then a wormhole sucks them into the RiOa universe. They are then attacked by Green Lantern rings, which upgrade them into Green Lanterns. The birds fly in a rampage into Oa, and get help from Blu (AU version) as a Green Lantern. Then the Birds realise that Yellow is missing, as he had gone to the Green Lantern Core. The birds go there. The pigs were involed in the Oa assult, and come back in spaceships and contructs. After dealing with the Pigs, the Birds, with Yellow fly into space, and do battle with the pigs there. After the Pigs get out of the way for good with King Pig defeated, They go to Shady's Warehouse, the final levels.
