Mario GameCube Game Where You Jump Into Paintings: Super Mario Sunshine

That game is Super Mario Sunshine (2002) for Nintendo GameCube.

How the Painting Mechanic Works

• Mario arrives at Isle Delfino for vacation.
• Equipped with FLUDD (Flash Liquidizing Ultra Dousing Device) – a water backpack with nozzles (Hover, Rocket, Turbo).
• The island is covered in goop (dark graffiti-like substance).
• Paintings act as portals: Jump into specific paintings (e.g., in the plaza, hotel, corona mountain) to enter distinct levels (Bianco Hills, Ricco Harbor, Gelato Beach, Pinna Park, Sirena Beach, Pianta Village, Noki Bay, Corona Mountain).
• Each level has 7 Shines + 100-coin Shine + secret Shines.

Why It's Unique

Unlike Mario 64's castle hub, Sunshine uses a continuous tropical island with the paintings as magical gateways. FLUDD's water mechanics (cleaning, hovering, rocketing) define the gameplay. It's divisive but beloved for its atmosphere, music, and challenge.
