The "potato statue" isn't really a statue. It's a weird, lozenge shaped boulder, set up vertically in the plaza. The boulder has only the vaguest resemblance to a giant potato: and to a very nasty-looking potato, the sort that you'd reject in the grocery store. The name is unofficial, apparently.
This nasty lump of rock is the rostrum for opinionated persons to unleash their nonsense on innocent passers-bye.
Perfect place for Fluke. However, since it seems she didn't draw sufficient interest to prop up her sagging ego, maybe she'll chain herself to the potato next. If she does, will someone please throw away the key?
