On July 15th, 12 super rare Nickelodeon character NFTs were auctioned on OpenSea for 24 hours. These NFTs are not a part of the main 10,000 Nickelodeon.xyz drop. They also cannot be exchanged for Slime in Nickelodeon NFT challenges.
1 NFT of each Nickelodeon character from the main drop was featured in the auction and each one completely unique. These NFTs can be distinguished by their memorable costumes the characters are wearing versus Slime-able characters from the rest of the collection that show off new poses, accessories, and outfits.
