Let's look at your sentence: "Look at all these toys! Some are soft, some can play music and some you can wind up to move! Which one to choose?"
There are a couple of small grammar points we can fix to make it clearer and correct:
- In the phrase "some can play music," it would be better to say "some can play music" as is — this part is fine.
- In the phrase "some you can wind up to move," it is missing a verb. It should be "some you can wind up so they move" or "some you can wind up to make them move." But a simpler way would be: "some you can wind up to move." Actually, "some you can wind up to move" is acceptable in casual speech, but to be perfectly clear, it's better to say "some you can wind up so they move."
- Also, the last question "Which one to choose?" is a bit informal. The more grammatically complete question would be "Which one should I choose?" or "Which one will you choose?"
Here’s a corrected version:
Look at all these toys! Some are soft, some can play music, and some you can wind up so they move! Which one should I choose?
