Is the really a treasure in this level and if there is has anyone found it?
You're gonna have to be more specific
Have you tried the guides at gamefaqs.com? I recall them helping me when I played Wario Land II.
Just checked, 50 levels, 50 treasures to collect, it must be there somewhere
I completed it once but it has been so long i can't remember
Me either, I got all the ending parts. Its a 2d game so it should be easy finding them.
Did you know that if you let wario sleep long enough in the first level rather than waking him, you get to a different story?
