Mad Jack was actually one of the bosses that didn't creep me out from DK64 as a child, does now tho..
I thought nearly every boss was creepy, paper k. rool.. even tho it was the ghosts and puffy fishes that scared me.. The giant puff-Fish... The dragon <-- Long time since I played now due to my new tv not being able to play old consoles

And Army-Dillo second-time...
I'm sure we'll get some recognicable bosses that will be funny, hard or even scary as cupcake... And let's hope it has a boss every Level, makes it more fun and rewarding.. Like u can get into the Levels With pagies, but to unlock the final boss you have to defeat all the bosses (Being equally hard, but the first one to introduce) This thread made me wanna plug in my n64 on my parents tv to play some..
