In a list of the 21 ainimals in SA2B there was an ainimal called a half fish but when I tried to find out where to find one by looking on your games page I couldn't find any half fish but I did find an ainimal called a swamp monster. Is a half fish the same as a swamp monster or are they different ainimals???
They're the same thing. They're also known as kappa.
