double'
class FrogStats { public static double GetAverageTongueLength(Frog[] frogs) { double sum = 0.0; for (int i = 0; i < frogs.Length; i++) { sum += frogs[i];
return sum / (frogs.Length);
}

Treehouse TeacherHi there! Well you have a couple of problems here. So I'm going to point them out and we'll see if you can get it from these hints.
- frogs is an array of frogs. So frogs[0] doesn't contain a number, it contains a frog What you actually want is the length of the frog's tongue at that index.
- you're returning a value from inside your for loop. Remember that a loop ceases to execute once a return statement is hit
Hope this helps, but let me know if you need more assistance!
