While venturing Utopia, the members of the flock have been captured - twice. The first time, Powerbomb Bird blew up the cage, releasing all birds that ended up in space. The second time, Super Red Bird and Ice Bird ran away before they could be captured with the rest of the flock. Luckily, Super Red Bird used his Uber Mask to contact the birds left behind, and he gets a message back saying they recruited a new bird: Aqua.
After the events of Cane Bars, the space pigs got angry themselves and captured the entire flock - besides Orange Bird, because they knew about his inflating ability, which could break the bird's prison. Orange Bird sets out to free the rest of the flock from the outside, but he's sure he needs help. Luckily, another alien bird comes to assist Orange... but this one is half bird, halk skunk.
After the birds are freed, Lazer Bird accidentally torches Utopia with his super-speed. The Orange, Ice, Aqua-Ice, and Skunk birds are chosen to undo this accident.
