Sir Mix-A-Lot is getting into the NFT space.

For National Colon Cancer Awareness Month, which is in March, and ahead of the 30th anniversary of his May 1992 hit “Baby Got Back,” the rapper partnered with developer META-X Studios. His first NFT collection, Bit Butts, is a way to raise money to fight colorectal cancer

“When the team at META-X showed me what they were doing, it was a no-brainer for me,” Sir Mix-A-Lot said in a press release. “And as an artist entering this new medium of NFTs, the idea of designing my own branded butts was exciting. Add to it the benefit of raising funds for a great cause like colorectal cancer, and wow! I hope everyone enjoys grabbing onto some nice NFT booty while helping others at the same time.”

The collection will include 6,666 unique, NFTs of derrières, which are hand-sketched, hand-colored, and hand-assembled by animation artists. Sir Mix-A-Lot also designed some of the rarest pieces in the collection. 

A share of each sale will be donated to the nonprofit Colorectal Cancer Alliance, which is on a mission to end the disease.

“We chose Bit Butts as our debut launch because we all need a good laugh right now for a good cause,” META-X Studios CEO Joe Sichta said. “Working with Sir Mix-a-Lot and the Colorectal Cancer Alliance was the perfect fit to showcase our firepower as an NFT creative factory, while raising awareness of a serious issue that can be embarrassing to talk about. We’re out to de-stigmatize colorectal cancer with a bit of ridiculous fun, and to donate a portion of the proceeds to support the work of the Alliance.”

The NFT collection will be available from March 28-31. Get more info here.

On a related note, the Colorectal Cancer Alliance launched a campaign that raises awareness around screening and prevention for “the preventable cancer.” The nonprofit partnered with Charlamagne tha God, Brandon “Jinx” Jenkins, Vashtie, and Mel D. Cole for the They Didn’t Say initiative.

“Too many of us have had friends or family that have been affected by colorectal cancer, so it’s important for me to speak out and help eliminate any embarrassment surrounding colorectal cancer screening,” Charlamagne said in a statement. “Hopefully this campaign will lead to more important conversations, screening and access to resources to help prevent this disease from further affecting our communities.”
