Nails

Nails are horn-like coverings of the tips of the fingers and toes of humans and most non-human primates, and also a few other mammals. They are similar to claws, and they are placed in the same anatomical location.

Maximus Mole had a habit of biting his nails when he was nervous. Minimus Mole once told him to stop biting his nails, but he told her he was worried since they had stolen some air conditioners.
