Super Mario Sunshine

The only direct sequel in the mario series. After gathering the 120 stars, (super mario 64) Mario, peach, and the royal toad toadsworth are on vacation to the beatiful isle delfino. However, their grand vacation soon becomes another goopy quest, and a sinister figure emerges in the form of a blue mario weilding a "graffiti brush". This vacation is over, but the fun (for the player anyway)is just begining.
