Additionally, given that Holly Hatchery is now an alien POI, the chances of finding the weapon there could be relatively better.Where to find toilets in Fortnite?Once the weapon has been acquired, players need to find two toilets, aka commodes, and then grab them using the weapon and launch them into the air. Thankfully, while the weapon itself is difficult to acquire, finding toilets is much easier.Reading on the toilet! #Fortnite pic.twitter.com/WFaw0zQcIY— Christopher Thomson 💙 (@topper_1) November 14, 2018Players can find toilets at almost any POI that has a building in the area. However, a good place to find multiple toilets would be at IO Satellite stations. Given that IO guards are posted there, players will find at least two toilets in each base.Here's a list of the IO satellite bases:Deep Woods Dish - Stealthy StrongholdDinky Dish - Southeast of Craggy CliffsDefiant Dish - East of Weeping WoodsDockside Dish - West of Dirty DocksDestined Dish - Southeast of Misty MeadowDiscovery Dish - West of Believer BeachDampy Dish - Southwest of Slurpy SwampReaders can watch this video for more information:Also Read: How to unlock Superman skin in Fortnite Season 7 - Challenges, unlock date, and more
