As usual, Bowser kidnapped Peach. But this time, he has taken over
her castle to doing some experiments : he created some evil Stars !
He tried it on Peach's paintings (which still aren't back to normal)
and... he did obtain completly different worlds, taken over with his troops ! Now that he knows that these "Ztars" work, he wants to use them on Mario, to prevent him to save the princess again.
He has prepared a trap, to have him absorb their negative powers !
Will he accomplish his plan ?
