Idk but it would make sense since snails have both sexes in each individual and can decide each time. Which is kind of super fluid.
Some fish can change sex once in life so that might fit better. But that's a lesser known fact I guess. The Nemo movie where they finally change to female is yet to be released.
Why not just pee in the toilet? Why pee on the toilet and then cover that spot with a sticker? This is why people hate public bathrooms. This snail raises many questions.
