Shooting both hands' eyes causes the head to open its eyes and throw rapid-fire but predictable-pattern fireballs at her from its mouth.

Rapid is bad, predictable is good. She doesn't want to get scorched while she takes the next shot.

She'll have to move fast, then.

After a while the hands 'wake up', the red eyes on the head close again, and it resumes its first attack pattern.

What? Boooo.

Oh well, she did it once, she can do it again.

And the glowing red eyes reveal themselves again.

Are the fireballs doing the same spread again?

Yes. Not exactly the same, as it follows her a bit, but mostly the same.

(She'll start to run low on arrows fast at this rate.)

That means she can get set up to get to a good position as quickly as possible once this bit starts.

She can toss a bomb, mix it up a little.

The bomb has no effect before the head's eyes are also shot.

But once they are, the head falls to the ground and opens its 'mouth'. That seems like a good place for a bomb.

Oooh, yes!

The giant head now appears cracked, and emits small amounts of smoke.

Rinse and repeat. After a few iterations of this.

"The path can now be opened for you, hero. Oh chosen one, what lies ahead is now governed by your fate, tied to the path you have chosen. Ascend and ring the great bell."

The giant head and two giant hands go back to their spots in the wall and emit a heart crystal. A pillar of sparkly light appears in the center of the area.

The path she's chosen? What?

Eh. Over to grab that heart crystal and then check out the sparkly light. It's shiny!

The sparkly light is sparkly. It will probably take her up to that hole in the roof, just going off context.

One way to find out. She steps into it.

It does.

That giant golden bell above her probably qualifies as 'great'. The rope pull is almost as wide around as Anna herself.

She wraps her arms around it as well as she can and gives it a mighty yank.

Not mighty enough, apparently.

Maybe a running start? Or swinging from it with the grappling hook?

Oooor both at once!

DONG. DONG. DONG. DONG.

Gosh that's a loud bell.

Ow ow ow her ears

Probably not the wisest course of action, in retrospect.

The bell has no comment.

Oh if only.

Please stop ringing now.

It soon runs out of momentum from her swing. The sound quiets and slows and falls silent. Nothing else interesting happens, at least not visible from here.

Right. So, uh. Bell is rung. What now?

Back down the tower, perhaps?

Not that anything or anyone is around to suggest it. It sure would be convenient if one could skip all the boring backtracking with a cutscene or something.
