A male contestant dressed in a roll of bamboo shoots must climb up a hill covered in foam, while avoiding giant acorns being rolled down the hill at him. The starting point at the bottom of the hill is covered in bushes.
The contestant is hit by rolling acorns and is forced back to the starting point.
"Well I guess after taking a few nuts on the chin, it must feel pretty good to be back in the bush".
All very legitimate and wholesome when taken in context.
