Question"interface hack" to make private nested class instances available to outer class methods ? Pin

If you are not familiar with this technique, I will publish a Tip/Trick soon.

Assuming you know how a nested inner class (which implements an Interface) can be declared 'private, and still be accessed by public methods in the enclosing outer class: which does make direct access to inner classes of the OuterClass prohibited.

Do you think the technique shown here is evil, undesirable, or ... ?

usage:
// necessary depending on use
// using NestedClassExample1;

OuterClass1 oc1 = new OuterClass1();

var cat1 = oc1.AddSomething(new Cat("cat1", "meow"));
var cat2 = oc1.AddSomething(new Cat("cat2", "hiss"));
var dog1 = oc1.AddSomething(new Dog("dog1"));

var cat1instance = oc1.GetSomething("cat1");
class:
using System;
using System.Collections.Generic;
using System.Linq;

namespace NestedClassExample1
{
    public interface ISomething1
    {
        string Name { get; }
    }

    public class OuterClass1
    {
        private List<ISomething1> Somethings = new List<ISomething1>();

        internal ISomething1 AddSomething(ISomething1 newsomething)
        {
            Somethings.Add(newsomething);
            return newsomething;
        }

        internal ISomething1 GetSomething(string name)
        {
            return Somethings.FirstOrDefault(smtng => smtng.Name == name);
        }
    }

    public class Cat : ISomething1
    {
        public Cat(string name, string sound = "")
        {
            Name = name;
            CatSound = sound;
        }
        public string Name { get; }
        public string CatSound { set; get; }
    }

    public class Dog : ISomething1
    {
        public Dog(string name, string sound = "")
        {
            Name = name;
            DogSound = sound;
        }

        public string Name { get; }
        public string DogSound { set; get; }
    }

    public class Tiger : ISomething1
    {
        public Tiger(string name) { Name = name; }
        public string Name { get; }
    }
}
