Eew, who wants to see the insides of a Hobbit?
It looks like the RotK cover has a hobbit near the bottom, to the right of Swan-head-guy.
If you think that looks phallic, you need to see a doctor about that. That’s about as un-phallic as it’s possible for a tower to look.
That’s not a hobbit – if you look closely, you’ll see that he’s further from the viewer than Bunny Ears, which makes him look smaller. You can see that Bunny Ears is standing on a rise closer to the viewer and Hobbit-like guy is not.
Look where it’s located.
