alright people for those who lost hope looking for the taranza keychain on world 6, EX stage 8 at the very end of it after you complete the picture with kirby over the years and kirby vs. king dedede there is the goal but if you look closer there is a moon. it's actually a secret door. enter it and fall. there will be some food, stars, common keychains, and a rare one, that's Taranza's keychain.
