Description
Blu (not to be confused with the spelling Blue) is the main protagonist of Rio and its sequel, and is a rare species of blue macaw that originated from a bookstore in Minnesota, taken by unseen smugglers and shipped to Rio, the same fate to later be suffered by the Birds, as their species (Red, Blue, Yellow, etc;) are also described as rare.

The Birds do not meet Blu until the very end of the episode Smugglers' Den, where he is locked up in a cage next to Jewel, the only other macaw in existence. He is later used in Jungle Escape as a usable bird in the final level that is connected to Jewel. When tapped, Jewel will fly forward with Blu being pulled behind her.

It is suggested that Blu may be used separately in future episodes, as hinted by a cutscene that appears after completing Jungle Escape. He is still armed with Jewel in Beach Volley however in Carnival Upheaval, he is separate. Blu, this time, has a new ability. Once he hits an object, he'll shake himself up causing spreading of objects.
