You can find diploid cells in all of the body cells of a frog, except for the gametes (sperm and egg cells). Here's why:

* Diploid cells have two sets of chromosomes, one from each parent. These cells are responsible for making up the organism's body.

* Gametes are haploid, meaning they have only one set of chromosomes. This is necessary for sexual reproduction, as the fusion of two haploid gametes (sperm and egg) creates a diploid zygote that develops into a new organism.

So, in a frog, you'd find diploid cells in:

* Skin cells

* Muscle cells

* Bone cells

* Nerve cells

* Blood cells

* Internal organs (liver, kidneys, heart, etc.)

Essentially, any cell in the frog's body that is not directly involved in sexual reproduction will be diploid.
