Tobias hides a coconut in a box

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Tobias drags a cart of heavy items into the square, and scatters the objects around the space. He leaves the heavy cart in the middle of the square, and adds a large, heavy sign for good measure. He hides the coconut underneath one of the boards that form the square. Mark digs around in the square for a while; while stopping to rest, he just so happens to step on the part of the board where the coconut is hidden, realises that something feels off about it, and locates the coconut. Tobias keeps the coconut hidden for 8 minutes 30 seconds, and earns fourth place.
