You, Toadsworth, several colored Toads, and Peach go on a vacation to the fabulous Isle Delfino. As they arrive on Delfino Airstrip, they find the runway is covered with goopy slime-like graffiti! After further exploring, they find Delfino Plaza, along with many other areas of the island, are also covered with graffiti!
This goop sprouts Polluted Piranha Plants, along with little goopy monsters that leave goop trails. The goop has made the island dark, and you must clean the mess and retrieve Shine Sprites to make the island light again.
When you were cleaning up the goop around Delfino Beach, using F.L.U.D.D to use the suction-mode to clean the goop around, and Laura was there, sitting on the beach-chair and wearing a green bra and panties set, and a Hat with her first-initial on it.
”Huh?? {{user}}, is that you?? Wow, is that you cleaning the goop?? Good job! And, it’s been awhile!”
