How to unlock the Queen of the Seven... Cheese? achievement in Shantae: Half-Genie Hero - Definitive Guide
As far as I can tell, Risky has EXACTLY 2000 HP.
The smartest method, as long as you have the magical tiara, is to hit her with Obliterate 79 times. This will leave her with only 25 HP. Then switch to mouse mode and finish her off. You could whip her three times with fully upgraded hair, leaving only 1 HP, but no reason for unnecessary risk at that point in my opinion.
If you don't have the tiara it'll be more bothersome to count. That's 249 whips with fully upgraded hair before taking down the final 8 HP with the mouse. More annoying but still manageable if you can keep count.
If you screw up, a dashboard and reload will take you right back to before the fight.
Edit: It still works, the achievement just popped incredibly late for me. Like a good 15 minutes later.
So what I did was fought her like that for around a minute and a half and then switched to the mouse and just spammed attacks at her, disregarding taking damage. I did go too early, and finally beat her shortly after another bad guy cycle. Probably took about 50 hits from the mouse after that 1:30 mark
Wail away at her when you can, then when she jumps up on the anchor, use Super Revive Dance followed by Invincibility. Take out the Tinkerbats, then repeat the process when Risky floats back down.
I have a few helpful tips to help you get this.
1) Don't use any magic (other than Invincibility if you have the Magic Tiara) to damage her. Instead, focusing on just the hair whip will help to plan this some.
2) Hopefully, by this point, you have both the speed and damage upgrades for your hair, so you should be doing streams of 8 damage with every hit.
3) The Mouse Dance (rewarded after completing Cape Crustacean (in other words, World 3)) and the Mouse Bite (found in Tassel Town post-boss) are required for this. While the dance is forced, the Bite is optional. With it, you will be able to do damage to enemies when out of mazes, but you'll be stuck with 1 damage.
4) Because of 2 and 3, go through one and a half to two complete cycles of hitting Risky as Shantae to whittle her health down some. Once you are ready, go into Mouse and remain there (until she departs via cannon). The choice places to wait for her are on either side of the arena, where she runs to after her jumps. Spam the Mouse Bite while being near the wall so you can: avoid her shots, avoid her feet, and avoid her sword swipes, all while still damaging her.
5) Despite my suggestion in 4, it will still take you a bit. It is better to be safe than sorry for this fight simply because of the boss trio this entire set is (and unless you want to keep quit/restarting the fight, going under her threshold is better than going over).
Risky Boots is the seventh boss in the game (see Pummeled Pirate) and you will need Mouse Bite in order to do this (see Relic Collector). Defeating Risky is normally not too difficult, but defeating her as a Mouse is a bit challenging because Mouse Bite only deals 1 damage. Only the killing blow needs to be in Mouse form, but there is no way of telling how much health she has left. You can (and should) weaken her using items and other attacks before transforming into a Mouse. Once you feel she is close to being defeated, turn into a Mouse and chomp away. A turbo controller will save your thumb a lot of pain.
According to optimusmart's walkthrough, you need to hit Risky around 240 individual times with the hair whip (at maximum upgrade) before switching to Mouse form and dealing the final bit of damage.
