Midas River

Stay left, get 4 Frog Coins and 10 Coins
If you follow the barrel section perfectly you should end up with 60 coins (stay left for 1st set, then bonk the barrel to end up right on 2nd set onwards, grab every coin you can from there)
Grabbing exactly 60 coins saves a text box when talking to the Toad.
(If you fall short, you can grab extras in Moleville Mines and Marrymore Inn, or just do extra Wiggler jumps)
