Bounty cards are able to Stash Terps, up to 3 cards maximum. After the player’s turn, the Bounty adds a Terp card from the top of the deck to it’s Stash. Each Terp in the Bounty’s Stash is no longer active or usable by the player for as long as that Terp is stashed by the Bounty.
See “Terp Purge” for more information.
