Well I don't want to CHEAT. Statues have been nerfed anyways.
You used to be able to use a crab engine to rapidly summon bunnies and/or goldfish during a blood moon, into a shallow pool of lava that would kill them but not destroy items to farm large amounts of money. They removed their money drop (presumably made a unique statue enemy instead of a statue that spawns the normal/regular/"real" one).
Can still get regular goldfish (the item) and sell for 1 silver each (99s a stack), or skeletons for the various items they drop. I'm still irate that developers nerf ANYTHING. They also dumbed-down a bunch of crafting recipes, much to my chagrin. Oh well.
