Lake Icky Gloomy is the lake next to Camp Lakebottom and Camp Sunny Smiles. The campers from both camps love to play in the water and sunbathe on its beaches. 

There are many creatures that live in these depths including Toothy the giant fish, a Lake Monster and the squid Slimey. It is not far between Camp Lakebottom to Camp Sunny Smiles, so it is easier to boat across Lake Icky Gloomy to either side to either pranking the camp or showing off. In the lake, there is a cave that leads to Camp Bottomlake, home to the fish versions of several characters.
