A fantasy turtle thing for a monster suggestion for a novel

Name: Graviturtle (Turtle or tortoise variants) (Please give it a better name, I suck at names) [ possible alternate names { Once again, I expect none of these names to be used, you can if you want , but I'm really just throwing all of my brains at the keyboard, and as you can see, I don't have many XD } ] - - - > Gravitoise, Gravoise, Giant Flying Spinny Shell Of Doom ( GFSSOD for short [ pronounced as Guffsod ] ) , [ was gonna try to think of another name, but I give up for now lmao ]

Concept: Giant Turtle/Tortoise that has spikes (The spikes are similar to bowser) and can change the gravity around it, whether it wants to make itself fly or smash you. It can fling you up super high with anti gravity, then massively increase it and SLAM you back down to earth, or just fling you off into the distance like a human cannonball. Can fling itself at enemies at VERY high speeds (Will not do so if shell has heavy damage) (When not flying via gravity powers, it is EXTREMELY slow) Can also make itself spin (forgot to mention that)

Vitality: High/Low (High with shell, low without it [Any attack that penetrates the shell or doesn't hit it in the first place] )

Discrete Parts: A Gem/Core/Something like that, on either the very top of the shell or the underside (probably underside, now that I think further about it [what with the spikes and all]). Massively decrease Mu count, and hinder all magic abilities.

Shell, VERY tough, but if penetrated, the flesh underneath is very soft. (If broken on the spine, causes paralysis {Full or partial depends on where it breaks} or death [For obvious reasons] )

(Still not 100% sure what a discrete part is exactly [My current best guess is basically weaknesses?] but ill try my best)

Element: Gravity

Mana Reserves: High

Drops: Shell pieces (Can be used for armor) More or less pieces depending on how much damage it sustained during the fight

Sorry for the chaotic mess this is XD

I tend to have ideas as I write that don't quite fit where I am, so I constantly jump around, resulting in VERY broken "sentences". lmao (As I'm writing these edits, I'm realizing that I am running out of bracket types... I've used ( [ { < all of these XD > } ] ) ) I NEVER expected to use more than ( [ ] )

I honestly never intended to write so much, just meant it to be one or 2 words for each category, but uh, I got carried away, as you can see, in quite a chaotic manner, but, that's how my brain works, jumping from this to that to the other, back to that, over the something else, back to this and so on until the end of time itself (or I just get tired of it or completely forget about it XD). Oh look, I hopped to another thought right there too. And there. ANYWAYS, I have really enjoyed your story so far, and I hope it continues for a while.

Just wanted to add some more names and other various things I thought of in the hours after I made the comment (also I have no idea why its in bold) also capitalizations and grammar and punctuation
