Unboxing is an obstacle in Double Dare. This obstacle consists of a package coming from Marc Summers from 1987 Double Dare Lane, Slime City, USA to Liza Koshy from 2018 Gak Tree Lane, Double Dare, USA. When contestants reach this obstacle, the package is "opened" by getting rid of the box to reveal a smaller box with a flag inside it. They then throw down the flag to move on to the next obstacle.
