Talk to the NPC in Rumbla Island

To start the quest, revisit Rumbla Island and head to the Island Plaza. From there, head north to Wilma's house and find the NPC outside her yard.

Talk to the NPC and they will give you a suspicious package to deliver to a building in Lottacoins Island. What exactly is going on here?

Look for the Address in Lottacoins Island

If you check your map while on Lottacoins Island, you'll notice that the side quest marker isn't even there. It's kind of annoying but don't throw the package into the sea just yet!

Enter the northwest building and talk to the receptionists. They will tell you that the package could be for their boss, who is at the third floor of the building watering plants.

Find the Boss on the Third Floor

Use the stairs next to them up to the third floor and try to talk to the boss about the package. Instead of receiving a response, the boss will rush back down.

Go to the Boss's Room

Ask the receptionists again where their boss went and they will suggest heading to the boss's room. Go up the stairs next to the building entrance then take the east exit upstairs.

At the end of this bridge is the boss's room. Give him the mystery package and watch the cutscenes to complete the quest! Claim your reward from the assistant and forget this quest ever happened.
