What OP products can you imagine which would, if ever sold, prove disasterous mistakes?
-Roranora Zoro's Santoryu Correspondence Course
-Book: Investing in Real Estate the Nami way (Step 1: Find a property sold by an inhuman monster for far above its true worth…)
-Grow your own Devil Fruit kit (After spending Y3000 for the set, the kids were very disappointed to find out they were just pineapples)
-Inflatable Fishmen for the pool (too many naughty applications) and the Life-size Going Merry raft (doesn't fit in pool)
-The Tony Chopper Halloween costume, with hat so large it makes most wearers lose their balance or at least covers the eyes. Variation: Reindeer horns and comical oversized hat for your dog, blue nose cap expected in time for Christmas
-The "McBaratie" floating restaurant franchise, which suffered from remarkably few customers at the middle of the pacific ocean.
