I'd go with the Blue Bots. They're so unpredictable.
I've died a lot of times from them, getting pushed off down a pit, mainly in Palace 3 and in the Great Palace.
I like all the other monsters. My favorite are the Ironknuckles and the bird knights.
The only way that could happen is if someone restarted the game from another save without the slingshot and bottle,
then went to where your sister paused the game to make it look like they didn't mess with it in the first place.
Toughest minigame to get a heart piece, I would have to say Fun Fun Island.
Even if you know the timing, it's still going to take good skill control & luck to land Link in the 50 spot.
Pumpkin pull became easy with the 'cheap' method & using C button instead of A to shoot.
Mine cart was just...
Shield bash is totally kool but you can use the sword to deflect the projectiles, both missiles & rocks.
The shield was 100% optional in this game when it came to killing monsters.
There was that one practice Log though, in the Training Hall, where you had to have it.
I like the final versions of the Wooden Shield and Iron Shield...I think it was called Braced Shield and Fortified Shield, something like that.
I used the Braced shield more than all three iron shields, just because I like how it looked.
I like the design of the Divine Shield (2nd form) more...
