We all know there were some unused or unfinished stuff in JJ2. Here are my theories for some of them:

The Tweedle Boss

Probably the favorite unfinished thing to most players.We all know it was supposed to be used in Psych, and here's what I think about it:
Tweedle was supposed to be in psych level 1, and not level 2 or the unfinished third level. The end of the first level just looks like an arena suitable for the boss, even though there's an 'arena like spot' in level 3

''Far out'', Psych level 3

Unfinished secret level DUH, although maybe it was supposed to be a bird level?

The rocket turtle
Yes, I know I already made a thread for this one, but i put it here anyway because of theories on other stuff
First of all, I guess you all know about the bird level in JJ1 where there's a boss with normal turtle sprites, where all you have to do to beat it is fly in a corner above it and shoot. Maybe the authors wanted to make a 'NOW I CAN GET UP THERE TO YOU NOW THAT I HAVE A ROCKET' revenge thingy in a Diamondus secret level? Y'know, Devan traveling back through time and all, and while he's doing that, he gives the turtle a rocket. Although I still don't have an idea why Diamsecr is basicly a copy of Diam1. Maybe the player was supposed to pass the same level with the bird, and face the rocket turtle at the end of it? The end area looks like it has enough space for flying or something.

3D view of bird

We can all guess it was supposed to be used in the 3D bonus stages, maybe the bird level was a level where the bird keeps moving forward and grabs stuff along the way, but it moves automaticly, and it was supposed to be moved around the screen in order to pick up as many as stuff as possible before the bird gets to the end... Something like that...

Purple potion

Probably a sugar rush potion... Designed specially for Labrat, or Psych perhaps?

Spinning and falling sprites of Devan

Maybe a Devil Devan phase took part in air? Maybe Devan was supposed to be playable in a secret level?

Boxing glove

Probably a gag that comes out when you step on it, and boosts you to ceiling hurt events.


What do you guys think? Also, do you have any theories on these or some other stuff?
