The Nintendo Reversible Mushroom Backpack originally started off a normal backpack, but then about 65 million years ago a meteorite struck it and caused it to split into two different backpacks; one being all black with a green One-Up mushroom while the other was grey, coated in power ups, and featuring Mario. However, Dennis Hopper kidnapped that girl from Broken Arrow and BAM! Now we have the adjustable Nintendo Reversible Mushroom Backpack. Wholly unique, this reversible backpack would be your standard two-pocket type but, as mentioned by the title, this badboy is REVERSIBLE! A reversible backpack! That's almost as crazy as a Super Mario Brothers movie, isn't it?
