From the Super Mario Wiki
Prince Pine is the prince of Jewelry Land and the son of King Fret. He and his father are friends with Princess Peach, and when their kingdom is attacked by Bowser during the course of Yoshi's Safari, she sends Mario and Yoshi to help.
In his attack, Bowser kidnaps Prince Pine and his father and steals the twelve magical jewels that unite Jewelry Land, splitting the peaceful kingdom in half, creating a Light Realm and a Dark Realm. King Fret was held in the Light Realm, while Prince Pine was imprisoned in the Dark Realm. After Mario and Yoshi defeat Bowser, Prince Pine is released, and with all twelve jewels recovered and united once more, Jewelry Land returns to a state of balance.
