Mario and Luigi walk past the portal of Ricco Harbor, talking.
Mario: 25 Shine Sprites already! We're moving fast!
Luigi: Why don't we get an ice cream to celebrate?
The duo walk around the corner and spot Shadow Mario with a gadget of some kind.
FLUDD: Mario, Luigi, get that object from him. That is our Turbo Nozzle upgrade. With it, you can move at a great speed!
Mario and Luigi step into Shadow Mario's view and he runs off with the Mario Brothers in hot pursuit. After the duo chase the imposter around the beach squirting him, the imposter finally falls.
Shadow Mario: No fair! You didn't give me a chance!
Shadow Mario runs away, and Mario picks up the Turbo Nozzle and equips it.
Mario: How fast does it go-OOOOO!!!
Mario zooms through the plaza, knocking over three Piantas with crates of glass trinkets. Luigi hides from the newly formed angry mob.
Mario: HHHEEELLLPPP MMMEEE!!!
Mario suddenly stops turboing.
Mario: What happened?
FLUDD: I ran out of water. Turboing uses a lot of water. Try turboing in the water. I keep refilling as you go.
Mario jumps into the sea and turbos for the next hour. He gets bored and turbos back to land. He runs up to Luigi, who is tied up and has fruit in his mouth.
Mario: Ready to go?
Luigi: (spits out fruit) I will be when you untie me!
FLUDD: When a new nozzle is claimed,
its nozzle box holograms over the island will solidify, making it possible
to switch when you break the box open. You two better find out where the
boxes are. There will be times when you'll need them.
