Shhwonk Fortress is an underground fortress in Paper Mario: The Thousand-Year Door where the Moon Stone and the Sun Stone are kept. It is beyond Petalburg and a few smaller stone fortresses. The Stone Keys found inside are used to open the pipe to Hooktail Castle.
Long ago, Shhwonk Fortress was a place of relief from monster invasions for Petalburg residents, but more recently it has been invaded by monsters and traversing to the ruins was recently outlawed without permission from Mayor Kroop. It is unknown when the fortress was built, but at least one of the fortresses located in the path to it is estimated by Goombella to be about a thousand years old.
Before Mario is allowed entry, he must participate in the 65th Super Fun Quirk Quiz hosted by a Thwomp guarding an entrance pipe. After passing the quiz or defeating four Clefts (if Mario fails the quiz), Mario is granted access into the fortress, which is infested with Fuzzies. After collecting the Sun Stone and the Moon Stone, Mario must fight a Gold Fuzzy and its Fuzzy Horde in order to exit the fortress.
