Cucco's Revenge Squad

A large group of indestructible Cuccos that will attack Link if he does sufficient harm to a Cucco in OoT. They appear wherever their more peaceful cousins can be found - Lon Lon Ranch, Kakariko Village, and even the bend in Zora's River. The only ways to escape the murderous group of poultry are to leave the area (they can't follow) or to mount Epona (Link himself becomes indestructible).

Failure to do one of these two things will swiftly result in Link's death.

They also appear in both the Light Overworld and the Dark Overworld in A Link to the Past, where the best option to evade them is either to enter a house or not to bully a Cucco up to 30 times.
