Where is the secret shop in mario super sluggers?

Question

I found a pass in the DK place to a secret shop. it kinda looks like its ghostly and everything, so i figure its in Luigi's Mansion, but I couldn't find anything. Help, anyone?

Answer 1

ok, after u beat baby bowser it should turn dark.when its dark, go to daisy's boat next to the light house. a kammak (or however u spell it's name)  will ask you for your pass. give it to him and your in the shop. if you don't have daisy's ship, go th peach's area and buy a pass from the shop :-)

Answer 2

at nighttime go to daisy cruiser which you can unlock by buying the cruiser pass at the shop at peach's stadium in the shop for 300 coins
