Im not sure what is not working about my code

namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            int totalLengthOfTongues = 0;

            for(int i = 0; i < frogs.Length; i++)
            {
               //Frog frog = new Frog(0);
               totalLengthOfTongues +=  frogs.TongueLength;
            }

            return totalLengthOfTongues / frogs.Length;
        }
    }
}

namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

        public Frog(int tongueLength)
        {
            TongueLength = tongueLength;
        }
    }
}
