Wopper

Wopper (a blend word for Wooden and Hopper) is a mod created by Ellpeck and Drullkus. It adds one block, the Wooden Hopper.

Wooden Hopper
The Wooden Hopper is the sole block added by Wopper. It functions similar to the Hopper, except that it does not have a GUI or any slots. It will automatically pull from inventories or items above it and put those items in the inventory below it. However, because it has no slots, it cannot collect items, just transport them, and it will not accept items if there is no inventory below it. Additionally, a Wooden Hopper cannot feed into another Wooden Hopper.
