Bored Ape Yacht Club (BAYC), Mutant Ape Yacht Club (MAYC) and Bored Ape Kennel Club (BAKC) collections jumped to top spots on non-fungible token (NFT) marketplace OpenSea on Thursday following theannouncement of an upcoming free mint for Bored Ape NFT holders.

As of Thursday afternoon, MAYC, a 19,439-edition extension of the Bored Ape NFT ecosystem, was in the top spot onOpenSea, recording a 13% bump in trading volume over the last 24 hours. The floor price of the collection stands at around 17.5 ETH, or about $25,000 – a more affordable entry point for those looking to join the Bored Ape ecosystem.

BAYC, the 10,000 edition flagship collection, saw a 237% boost in trading volume over the last 24 hours, according to OpenSea, with its floor price hovering around 78 ETH ($111,000). BAKC, a companion collection for BAYC holders, also saw a 46% boost in trading volume in the past 24 hours. Its floor price stands at 9.1 ETH (about $13,000) as of Thursday afternoon.

The pump comes a day after parent company Yuga Labs announced that it would soon offer a “Sewer Pass” NFT mint that could be claimed for free by existing holders of BAYC or MAYC NFTs. Holders of a BAKC NFT can also pair their pet with a BAYC or MAYC NFT, which allows them to mint “a higher-tiered Sewer Pass,”according to Yuga Labs.

Each Sewer Pass grants access to a game called Dookey Dash, which instructs holders to reach a score above 0 to validate their Sewer Passes and "transform them into a mysterious power source." What this means remains unclear, though NFTs created from this month-long experiment will be part of a bigger narrative experience called "Chapter 1" at a later date,according to the project's roadmap.

Notably, Dookey Dash can be played an infinite number of times by Sewer Pass holders until gameplay ends on Feb. 15 – meaning that Sewer Passes will be able to be traded on the secondary market, allowing those outside of the Bored Ape ecosystem to participate.
