Theres this one part of the casino that you go into ,i think it's a wall,and once you go through the right spot you have to fight king boo,he sticks his mouth out at you so when your battling him there will be fruit falling from the ceiling and you have to throw the spicy food in his mouth

Sirena Beach - Episode 4: The Secret of Casino Delfino
Talk to the hotel manager outside the hotel to get in. Talk to the Pianta next to the reception desk to get into the casino.
You need to get 777 on both left and right Jumbo Slots. For the left one, spray each slot individually. Spray the right one and all 3 slots spin (if a ghost appears, spray until visible, then jump on it).
Then spray the 16 ? Panels until the picture of a Shine Sprite is revealed (? Usually stay flipped in pairs).
Enter the green pipe and complete the secret level.

Run past 2 sliding cubes in front, down middle, then jump onto moving cube.
Jump onto next platform. The 2 cubes in front and 1 to right smash together at the 1UP mushroom to the right, then return to the front & right of this platform, respectively. Left cube just slides up and down. 2 more sliding cubes at the end of this platform.
Jump to rotating cube (move across it's surface 3 times) and jump to wooden block ahead.
These 4 sliding blocks don't slide all the way into the left and right walls, so the only danger is not pressing A at the right time when jumping across them.
Jump and cross long rotating block in front. Jump to large rotating cube.
Head for upper right orange corner, then right to flat surface (with green and yellow corners). Run to lower right blue corner, then to surface with blue and orange corners.
Jump to platform and get Shine Sprite.
