Here pattern is like this:
- Shoots one ring, doesn't jump high at all.
- Hit her once, shoots another ring, jumps a bit higher.
- Hit her twice, shoots another ring. THREE rings are bouncing around, and she jumps fricking high.
Going in the battle with a power up is recommended. It's pretty easy to get over-whelmed near the end since three rings are bouncing around. Lemmy, if I remember correctly, wasn't as annoying with those ball since you could jump on them.
