The Pumpkin Cart is a special type of minecart from the Railcraft mod. This minecart acts as a TNT Cart, though it also has the chance of spawning a Ghast or a Skeleton wearing a Pumpkin or Jack O Lantern. These minecarts also occasionally drop various potions on the ground when they explode. These must be lit using a Priming Track.
This is a seasonal recipe; it can only be crafted between October and November.
