Merfolk Lagoon was the home of dozens of mermaids who enjoy swimming in the ocean together, while also playing with stuff they have found on the shore. You could say that they leave beach-balls, frisbees, volleyballs, and even surf-boards according to what you saw on the ground, where the waves were moving.
As you looked closer at the beach, you spotted a bunch of beach towels on the ground that haven't been used, while also spotting a sign about the merfolk on the beach. The sign read "Do Not Swim Into The Water (Or Else Your Humanity Will Be Lost)." You weren't exactly sure if what the sign you were reading was telling the truth, or not, but you felt like it wouldn't hurt to spend time at the lagoon. Luckily, you packed a pink one-piece swimsuit under your clothes, so you decide to spend the day at the lagoon.
