Mario and Luigi jump in the cannon and blast off to Pinna Park. However, the ride could have been smoother. Mario lands headfirst in the sand, and Luigi is up to his neck in sand when he comes to. Both Brothers get free a few minutes later.
Mario: Let's visit the park!
The duo walk up to the entrance to find it locked.
Luigi: Mamamia! What's going on here?
As if it was the answer to his question, a Bullet Bill lands right next to Luigi and explodes. Luckily, the Brothers jump and avoid getting caught in the explosion.
Mario: I'm guessing that!
Mario points to a distant cannon on the opposite side of the beach. In it is an angry mole, and the cannon shoots a Bullet Bill at the Brothers.
Mario: Spray it!
Luigi sprays the Bullet Bill and it explodes in midair, dropping coins.
Luigi: Hoo boy! How did you know?
Mario: We did it the last time we were here, on the roller coaster.
Mario and Luigi dash for the cannon, spraying every Bullet Bill coming after them. When they reach the cannon, the mole jumps out.
Mole: You think you're so clever! Well, you won't beat the great Monty Mole!
Monty Mole jumps back in the cannon and starts to throw Bob-ombs at the duo.
FLUDD2: Quick! Spray the Bob-ombs to deactivate them. Then, throw them back at him to defeat him.
Luigi: You must have a built-in strategy guide!
The Brothers work together to defeat Monty Mole. Mario sprays the Bob-ombs, and Luigi throws them at Monty Mole. Eventually, after three hits, the mole gets blasted out of his own cannon out to sea. The cannon repositions itself suddenly.
Mario: You thinking what I'm thinking?
Luigi: Secret level!
Mario and Luigi jump in the cannon and get blasted to a secret level. However, Shadow Mario steals the FLUDDs like always. Mario and Luigi appear at the beginning of a line of blocks. At the end is the Shine Sprite.
Luigi: This isn't too bad.
Luigi steps on the first block, which turns black.
Luigi: ... That can't be good...
The block disappears and Luigi falls, loses a life, and reappears beside Mario.
Mario: We need to move fast!
Mario and Luigi sprint across the blocks before they can disappear. They reach a solid block as a safe spot to rest. After a five minute rest, the Brothers run across some more disappearing blocks with blocks sliding past them to knock the Brothers off. The Brothers past and reach the second safe spot.
Luigi: *pant* Mario... *pant*
Mario: *pant* Yes, Luigi? *pant*
Luigi: *pant* Are we almost there? *pant*
Mario: *pant* Just one more leg to go! *pant*
Mario and Luigi gather the rest of their strength and dash to the Shine, with the blocks disappearing faster than before. Nevertheless, the duo makes it to the final platform with the Shine. Mario and Luigi both touch the Shine and try to do the Shine Dance, but collapse in exhaustion.
*****
Mario: Luigi?
Luigi: Where are we?
Mario: Outside the cannon...
Luigi: ... Was it a dream?
Mario and Luigi wake up entirely now and realize a Shine is in their hands.
Mario: Um... Woohoo?
Luigi: Er, on to the next Shine?
