ok,mariofan1976,u haven't ever noticed the sun things on the ground,there little tunnles look around on the floor of delfino plaza,u will see them,there r about twenty,wen u see 1 go up to it and ground pound it,u will then be in a tunnel with the classic "tunnel mario" music.To beat the gopher is a little tricky,come close 2 him,but not close enough 4 him 2 go in his cannon,wen your that close he will shoot walking bombs,spray them,u only have about 10 seconds after u spray them so u will have 2 b quick(sorry about all the abreviations i'm using) pick 1 of the bombs thet u spray and toss it at him,he will get confused and start shooting more,faster do this 3 times and u will win!!!But then u have 2 do an obstacle course i beat it the 1st time(lol) but it can be preatty difficult.ok after u spray the giant shine thing a shine will appear way at the top,there is no way u can get this without unlocking the rocket nozzle in delfino plaza,i think u need 30-40 shines to unlock it but i could be wrong. i really hope this helps for u to be a better gamer!!! Peace out!!!
