You can very rarely obtain a Scuttlebloom furnishing by looting Scuttlebloom plants in Murkmire. Personally, I had poor RNG with those little flowers ... but maybe you’ll have better luck, @Rex-Umbra.
From patch notes 4.2.5:
“ Be on the lookout for the elusive (and tiny) Scuttlebloom! Sneaking up on this little guy rewards you with a temporary boost to your run speed, as well as honey, alchemic grease, or very rarely, a docile Scuttlebloom of your very own to place in your home. Be careful though - if they sense your presence, they will duck underground until they sense the danger is gone.”
