Why can't seeps go on rock golem corpses?
It makes sense that they can go through rock, and as their name suggests, rock golems are made of rock.
Oh, but everything else they move through is massive, like walls and doors.
Smashed rock golems are single obstacles with free space around them, even if it's not enough for Beethro to squeeze through - and seeps (with the exception of killing Beethro, which would make them a bit dull if it were missing) can to move through thin air as much as Beethro can walk through walls.
