I'm undertaking some experiments with Clone Tag Team 2, and I've been wondering if it would be possible to make a Boss Key appear by using an activator instead of defeating a Boss.

I'm working on my own kind of Boss battles in CTT2 where instead of an actual Boss, Mario is placed in a room with certain enemies he has to defeat. I can easily make a Door appear which leads to a Flagpole, but I wanted to know if there is any way I can make the Boss key appear instead.

I have my doubts though, as it seems that the key is just a "part" of the Boss itself. But even then, would I be able to somehow defeat a Boss (that is hidden off-screen for example) with an activator, which will then make the key appear.

What do you think? Possible?
