The Donkey Dupe, also known as the Cact-Ass Dupe, is a duplication exploit found in March 2017 that is larger than the 11/11 Dupe. It is a simple dupe exploit involving breeding donkeys and teleporting them to the Nether. It remains one of the largest dupes in 2b2t History. It only lasted for three days but was the most overpowered dupe.
