There is, you just need to play until you get the ghost and pumpkin to line up. Took me a handful of tries but you can always get more coins by going to the loan shark out front and then the coffin game.
The cave is from an older build, instead if you go to the left of the mart you can see the kids hanging on a cliff. If you first jump on a wall nearby you can parkour up there. If you have further questions you can check the wiki.
