Got Somethin' Good! is a small tune that plays when the player picks up very useful items like maps or when winning back Duster from the DCMC at Stone-Sheet-Clippers.
Got a...[]
Got a... is a tune in Mother 3. It plays in Chapter 1 when Flint finds a scrap of cloth from Hinawa's dress and when he finds one of the shoes that Claus always wears. It is a disconcerting variation of the tune Got Somethin' Good! that usually plays when a character obtains an item.
