i really wish you could mix at least the normal/special badges with the utility ones. itd be real nice to see the ! blocks or play with the only one powerup type ones but i couldnt bare not having jet run
I've found one other similar area. In the level rarrghs in the ruins. after you activate the first spinning platform there's an area that is only accessible with the block badge. Found it when playing around with the bubble power up.
Still made me upset that the one powerup badges were at the end of the game. I just wanted to be an elephant. Had to fight trunk and tusk to keep it only to get a badge at the end when it was no longer necessary or relevant.
