What can you give the guy in the Riches mansion in Undella town?

Question

There is a guy in a karate suit in the Riches Mansion in Undella Town who wants rare items.
What in the world do i give him??????

Answer 1

He want Relics if you go to Undella bay Have a pokemon that has Dive and go to these dark spots in the sea there should be Pokeballs there some plates and some Relics

Answer 2

the man excepts flutes. If you use dive in the undella ocean you find these relics. Because these relics and plates are so precious, even the official guidebook won't give you the price of certain items like the relic vase. I tried trading the relic vase for I believe 500 000 pokedollars! My friend said that trading him a relic crown will give you WAY MORE then that!

Answer 3

One of the things is flute you have to ask the treasure hunter in the way from lacunosa town to undella town each time you ask him for the treasure you have to go to the date setting and then going forward a day then ask him again until He give you flute I get a yellow and black flute from him
I hope you use it
