Similar to the idea of the Noble Decadence merging the King and Queen Slime's pets, what about an idea to merge the Mechanical Bosses' pets into one item? No real functionality other than being able to have all three Master Mode pets out at once, and could be combined with a unique fourth item that only drops when you defeat all three at once (or adding the Mechanical Minecart as the fourth item).
