Tomato Adventure - Oops Boss Fight - Hardest Difficulty

I've been playing Tomato Adventure lately, now that is fully translated.
Here's the first of the six Super Kids: Oops.
At first she can be a bit difficult, since you probably won't have good equipment at the moment. Even if you have high HP she deals a lot of damage, something that your low defenses can't help about it, and Oops can lower your defenses even more.
The main strategy is trying to break her Wind-up Bath first (or else she will heal herself at the end of each turn) and then breaking her Miracle Mirror. After that you'll only need to attack Oops' head with your stronger attacks.
