Star Piece (Super Mario RPG: Legend of the Seven Stars)

The Star Pieces are important items that appear in Super Mario RPG: Legend of the Seven Stars. They are the main focus item and, after hearing this from Geno, Mario and his team collected them throughout their journey.

History
The Star Pieces originate from Star Hill where it was broken apart by Exor when it passed through Star Hill and entered Bowser's Keep. Mario managed to find one without knowing it's real purpose but it was after getting the second Star Piece from Geno where he learned why they are needed. The Star Pieces are needed to help grant the wishes of those who have wished. However, this cannot be done with Star Hill damaged and the Star Pieces are needed to restore it back to full power. Star Pieces are usually guarded by members of the Smithy Gang though others can be found laying around in areas or guarded by other bosses (such as Jonathan Jones).

Blue Star Piece
The first Star Piece is found in the Mushroom Kingdom. After Mario and Mallow arrive back from Bandit's Way after defeating Croco, they find the town overun with Shysters. Mario and Mallow enter the castle where it is taken over by Mack of the Smity Gang. Mario and Mallow defeat him in battle and Mario earns the first Star Piece.

Green Star Piece
The second Star Piece is found deep within the Forest Maze. It was found by an Aero who has given it to Bowyer. Geno arrives and attempts to stop Bowyer from firing Aeros and to hand over the Star Piece but Bowyer doesn't' agree to. Mario and Mallow join Geno in the battle where they all fight against Bowyer and win. It is then where Geno tells Mario and Mallow about the importance of the Star Pieces and why he has came from Star Hill to retrieve them.

Orange Star Piece
The third Star Piece is found deep within Moleville Mines. This Star Piece is guarded by Punchinello who actually isn't working with Smithy. However, he does fight Mario and his team hoping to become famous.
