Strangely, the balloons in Angry Birds doesn't have any ropes to tie with the objects but it still can hold objects and pigs in midair.
They are seen in the 2012 spin-off as usable items.
In Bad Piggies, red balloons are used as items for Ross to use. When attached to a wooden box (even when Ross is inside it), it will gain weight, not going up, even fast.
In Angry Birds 2, it's normal balloons but their length is almost long
In addition to appearing as objects in the game, balloons have been used by the Pigs to steal eggs in opening scenes or cutscenes.
