There are 9999 Yellowcake Park Mutants in the whole world. Each one of them is uniquely shaped by the extreme conditions of the Aaǝ Exclusion Zone, where no human would be able to survive.
All the mutants of Yellowcake Park will be stored eternally on the Ethereum Blockchain as ERC-721 tokens. YPM token holders will be the only dwellers of Yellowcake Park.
