Check the map above to see the porta-potties in all of their lavatorial glory. Here’s some further context on where to exactly find them, if you’re not much of a map person. Four porta-potties are located on the northern outskirts of the Coral Castle. Two are in Corny Complex, and three are in Catty Corner.
After traveling through one of these porta-potties, you’ll net yourself a whopping 30,000 experience points. Not too bad for a fairly straightforward and easy challenge.
