I've decided to replace Cracked Egg with ultra Eggstinct

They normally only appear together (their combined power makes them able to do this)

But they can might appear alone in a bad situation

Basically the ultimate boss trio

The final challenge of the game

Eggyhead: The learning god
Inkmatas: The Inkstone witch
Collector: Creation humanized

Their canon theme is ultra dripstinct

and occasionally they use attacks from other bosses
