These non-fungible tokens were created for demo purpose of Litemint NFT contracts on Stellar.
Open the Tokenz Store demo shop in Litemint to interact with these non-fungible tokens (NFT).
You can buy, sell and trade them on the Stellar DEX and even breed them.
For now Stellar Labs can be used to build 'traits' transactions to create offsprings, the wallet will provide such feature soon.
Visit the Litemint blog to learn more about the NFT contract implementation in Litemint.
