The Orfruit is a whistling pinwheel that appeared in Annoying Orange: Luck o' the Irish and Annoying Orange: Back to the Fruiture. Orange and Pear love playing with it, although Pear is the last known person who possessed it until Future Orange took it to prevent it from entering the wrong hands. It has been known that it is the most powerful weapon known to man or fruit, as when used correctly, it can destroy anything. The fate of the pinwheel is currently unknown.
Irish
The pinwheel first appeared when Orange wished for it, with help from the Leprechaun. Leprechaun had it taken away so he could finish more quickly, and was later found by Pear, who wouldn't give it back.
Fruiture
Evil Orange, posing as Future Orange, transports to the past and reveals to Orange of the pinwheel's true identity and that it was the most powerful weapon known to man (or fruit). Pear, not wanting to give up his pinwheel, doesn't give it to either of them. The real Future Orange teleported to the present and took the pinwheel, using it to kill Evil Orange.
