Age-appropriate grammar check for a 7-year-old: describing a snake, crab, and monkey

Here are corrected versions of the sentences. I made the grammar clearer while keeping the playful tone:

1. Snake: I take off my old skin as if it’s a dress!
2. Crab: I wear a strong shell instead of skin!
3. Monkey: I have nails, like you do, and other animals have claws.

Notes:

• Keep contractions (it’s, I’m) for a natural voice, but ensure they are correct in context.
• “Take off my old skin” is common for snakes; “as if it’s a dress” is a fun simile.
• “I wear a strong shell instead of skin” is clear and accurate for a crab.
• For consistency, you can say “I have nails, like you do, and other animals have claws.”
