The name `frog' does not exist in the current context

Need help with the for loop to return the average length of the tongue of frogs. Can anybody help me, get the above error. Thanks in advance.

FrogStats.cs 
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            double sumTongueLength = 0;
            int i;
            for(i = 0; i < frogs.Length; i++)
            {
                sumTongueLength = sumTongueLength + frog.TongueLength;
            }       
            return sumTongueLength/i;
        }

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

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

You are getting that error message because the variable "frog" has not been assigned anywhere in the program. I think what you need to do is to use an index for each of the frogs in the array of Frog.

sumTongueLength = sumTongueLength + frogs[i].TongueLength;
