The Cobalt Star...a mysterious object which powers E. Gadd's time machine. Its 6 pieces are scattered throughout the Mushroom Kingdom.
To save Princess Peach, Mario, Luigi and the Babies must gather at least 5 of the shards to open the gate to Shroob Castle and save Princess Peach.
But, there is a hidden secret behind the Cobalt Star. Some people claim to see a face
inside the star, others think that the star shards have minds of their own. Only Princess Peach can shed some light on this mystery.
In the end, it turns out to be Princess Shroob's older, bigger, tougher sister...and just when she seems to be beaten, it turns out she isn't finished yet!
