Classic Zelda things I'd like to see in the next open world Zelda

 For now, Zelda will be doing the Open World sandbox thing... Breath of the Wild and Tears of the Kingdom have done a great job in being great Zelda games on this formula. Problem is that a lot of Classic Zelda things are missing, from items to enemies and lots of things in between.

Instruments:

Whether it's a recorder, an Ocarina, or whatever; instruments are something missing from these new Zeldas. They don't NEED to be these Overpowered McGuffins that control time, space, and weather. But some classic songs could have some effects, like say, olaying Epona's song in a field with horses makes them more docile. Playing Ballad of the Windfish could kill Pols Voice monsters instantly. Playing Saria's song could make nearby hidden Koroks react to it... or as a nod to the Original Legend of Zelda, play the Warp Whistle theme and a whirlwind appears, but only at specific locations... just to name a few things... a "Musical instrument rune" would've been a lot better than the "Map Rune" we got in TOTK, especially when "-" can summon the map.

Trasure Gadgets:

This is exactly that, things like The Hookshot, Pegasus Boots, Iron Boots,  etc. The weapon type treasures should have limitations but not fully break. Let's take the Hookshot:

-only works on wooden surfaces for climbing.

-has same combat durability as the Master Sword.

-recovery could be sped up if one uses the right supplies like say: oil, iron (sacrificial weapons), and say, diamonds. 

Yes, I "nerfed" the Hookshot a bit, but the open world Zeldas tend to nerf items, mainly weapons. Pegasus boots could worl similarly to Zonai devices that require battery power for their effects to work. 

Enemies:

I already mentioned the Pols Voice as an enemy that should return. Right out of the bat here's a few that I'd like to see:

Dodongos:

They would've been a cakewalk in Breath of the Wild  with the unlimited bombs. But in Tears of the Kingdom, bombs are a rarity and having bomb gobbling bosses can be a scary thing. Now box in Link in a canyon with a few climbable areas now add rain, you're welcome! 

Aquamentus:

The FIRST Boss from Legend of Zelda should make a triumphant return. It could return as a boss enemy OR as a special Underworld steed.

Lanmola:

While Molduga is a more powerful takes on the Moldrom, Lanmola can work as a generic desert enemy that requires to kill bit by bit.

Manhandla:

Big Plant boss, but While it was in Hyrule Warriors, I wanna see it return in a normal Zelda game.

Digdogger:

He'd be a perfect miniboss and also justifies the use of the Musical instrument...

I know that most of my picks have been OG Legend of Zelda based, but to be fair OG LoZ is what got me into Zelda and, Breath of the Wild, and to an extent, Tears of the Kingdom seem like a sort of love letter to the original game.

But the top of my head when thinking Zelda always gravitates to Legend of Zelda and Link's Awakening. Now TOTK comes in third place with Adventure of Link rather high up there. 

Be grateful that I'm not asking for HIS return...
