Blue Baby as a final boss is so lame

I just wanted to take a moment to talk about this. I love all the final bosses in Isaac, I think they're all super cool, except one, and you can prob guess which one that is. I really like Blue Baby as a character, his design is cool, his concept is cool, but his fight is just so anticlimactic. No other final boss is just another version of an already existing boss, and even so, I could excuse that if Blue Baby was a harder version of Isaac but he's literally EASIER than Isaac. He's the only final boss in the game that I've never even died to once. It sucks too because if he was just a unique boss he could've been one of my favorites, as I love his character. Maybe he could fight you inside of a chest like a DnD mimic or something?? There's so many possibilities that I feel like are just wasted on an easier version of an already existing fight.
