Rock Golem Head

Placed, it accepts flower seeds and grows them out of the top, which makes it decorative rather than useful: herbs will not go in, so it is no replacement for a Clay Pot. Left empty on the surface or up in space it grows wild grass on its own, which is the low effort way to use one.

Clearing the plant is the fiddly part. Whatever is growing up there ignores ordinary tool swings, so you cannot tidy it by walking past with a sword out. It takes a pickaxe, a drill, or one of the regrowth tools such as the Staff of Regrowth.

However you face it, the eyes turn to follow you around the room, which is either the charm of the thing or a reason to keep it out of the bedroom.
