This cheap and fast warped and crimson fungus farm actually isn't an April Fools; it might be hard to believe, but thanks to cart yeeting (and @inspectortalon 's cart-yeeters), this farm is able to farm fungus at the fastest rate possible whilst using over an order of magnitude less redstone components than current max speed designs.
