The idea is to do challenges with bosses that are related to something, for example (something metal) U.C.O., Mysterious Ship and Iron Chef are attacking you at the same time. (something with an egg) Mystterious Ship, Mother-Hen Ship and Blast from the Past. (something related to chicken) Military Chicken, Party Chicken, Sweater Chicken, Magnetic Manipulator and in addition 6 Large Chickens. (I know the last one is the hardest) Regards, recruits!
Hard bois challenge?
These are boss challenges, some easier and some more difficult. This idea is underdeveloped. There may also be rewards.
