Here are three kid-friendly rephrasings:
- I have no fur, but I slip through the dirt easily. My sharp teeth chew roots and I dig tunnels to live in.
- Even though I'm hairless, I glide through the ground without trouble. My sharp teeth nibble roots and I make burrows.
- No fur covers me, yet I move smoothly under the earth. With my sharp teeth I chew roots and dig cozy burrows.
