Take out your clawshot and aim at it
I'm pretty sure that there is no such thing as a red suit in Twilight Princess. There is only green, blue, and gold.
There is no whip... if your talking about the grappling hook, you get it in the ice temple
to the bridge of eldin
at the caslle villge thing w/ the cats in frot of it
Probably not (if you noticed midna shattered the mirror of twilight, the only thing connecting the twilight realm to hyrule, in the cutscene after the credits of twilight princess), unless Myamoto decides to do a direct sequel to twilight princess, which isn't totally out of the quuestion; see "Majora's Mask".
When it opens it's mouth slash at the thing that holds it together
There's no one or thing that goes buy that name.
I'm not exactly sure of what you are talking about, but the thing I think you saw was a Poe you can defeat these by using your senses as a wolf. I don't think that you can defeat this poe at this moment until you get the ability to transorm into a wolf at will.
Yes she is. In fact the 2 part opener was called Princess Twilight Sparkle. But the funny thing is that her brother has been a prince since day one. Therefore, she already was a princess technically. But now they actually made a big deal about it. XD
You can't save at the end. It's because they didn't make a part that there is no monsters and that sort of thing.
If you count the Cavern of Ordeals, yes. It is harder than any boss to beat the whole thing, but worth it.
You'll have to restart the game. Just kidding, all you have to do is warp out.
