The Orange Bird, or Globe Bird, is a recently announced bird that made its debut in the Ham'o'ween episode. It first appears in Ham'o'ween theme 1-4. Although being the size of a Red Bird (Although in the Ham'o'ween promo, they're seen as much smaller than the Blue Bird), once launched, after two seconds after collision, the Orange Bird instantly expands to enormous size, even bigger than the Big Brother Bird. About 5 seconds later, it deflates and pops. Its ability is almost the same as the Black Bird.

Although it expands to a huge size, its strength doesn't change when flying. When the player taps the screen while the bird is flying, it appears as it would cause great damage, but it does minimal damage when fired this way.

Trivia

 * The Globe Bird inflates explosively like a balloon; however, unlike the Black Bird, its expansion doesn't displace all the objects within its blast radius, rather, it forcefully expels the objects closest to it but objects just slightly hit at the extent of the inflation will barely move and even stay in place. This makes the Globe Bird most effective when its right next to the desired target, as even though it may hit objects further out, it does little to nothing against them.
 * It can destroy objects it comes into contact with while deflating.
 * In Ham'o'ween at first due to the lighting of the episode he was thought to be a baby yellow bird in a costume.
