Heh, interesting thread choice.
Hmm, I'll tell you something that I tried that actually DID work that I don't think was meant to. In the Sky Keep, I managed to rearrange the rooms in a way that allowed me to completely bypass the Earth Temple room, although I'm fairly certain I wasn't supposed to! x3
Mine mostly revolve around the bug net.
I tried catching fish with it, remlits, npc heads and merchant' s wares.
So did I, most especially the remlits. Haha, trying to catch NPC heads sounds fun though, didn't try that one. xP
I tried catching fish as well XD
One of the weirdest things I tried was completing the eldin volcano 'prison break' thing without the slingshot. I found that I could get past a lot of the seemingly impassable guards by using the clawshot to push them back. I'd just keep pushing until I could run past without being seen. I had to go back eventually though as you can't get past the guard tower without it.
I managed to find a few small glitches that allowed me to get to places that usually weren't possible to reach. But often there'd be a barrier stopping me from going any further anyway
Oh, the clawshot? That's a pretty good idea. Originally when I tried to get through there, I hadn't even realized that I was supposed to retrieve the slingshot before doing so, so I actually got passed those guards without using any items at all. If you walk into their range of vision a few feet away from them, rather than seeing you immediately, they perk up as if to think "oh, is there something over there?" (there must be something seriously wrong with their vision since they can't clearly see Link in front of them....) at which point you have time to circle around them and run through the opening they left unguarded. Using this approach, I got to the guard tower as well...only to realize that I had indeed missed something crucial, and thus went back to retrieve said slingshot, for the guard tower which was impassable without it.
--Oh, oh! Here's a good one: you know the claimed 1:1 sword play that this game features? Well, I tested this right away after I borrowed the knight's sword from Eagus and was actually let down that it didn't work... I took my wiimote and pretended to stab myself in the chest with it. Er, it's not really a surprise that the game wouldn't let me, but I was still bummed about it. xD
Try stabbing yourself? Ah, I forgot to test that one myself, haha.
Attempting to throw a remlit off a ledge and making it stay down there.
Yeah, I tried throwing them off the edge too. Then was surprised to see them flutter back up, flapping with their ears...
Tried getting food at the Bazzar. If you sit at either table, the guys start up a conversation with you and one of them mentions waiting forever for food. So I literally sat there for ten mintues waiting if she'll actually give you food.
Heh, that's funny. It's really too bad, because when I sat down to talk to those guys myself, I'd been hoping that the woman in the back would come over and serve me some of that fine soup she was so invested in making...
Before I got the whip, I tried running up to the horn blowing enemies, and tried snatching their horn with the bug net.
Awesome. xD For me when I got the whip, I'd been hoping it'd work a lot like
The Wind Waker's grappling hook, where I could steal items (in this case treasure items) from enemies that carried them, such as Chuchus and Keese (and imagine if you could steal the Lizalfos' lizard tails by latching into them! Too bad...) but that didn't quite work out the way I'd been hoping...
Trying to land on the top of the waterfall in Skyloft... After 20 try's, I figured out that you can't land on the top...
Same, it puzzled me for a while why it wouldn't let me do that, and afterwards had me convinced with disappointment that there was no way onto that little island. That was until I got the clawshots....
I tried throwing the large jars in the Knight's Academy at the grumpy canteen lady, the results are rather hilarious.
Yeah, she started threatening to have you expelled from the Academy or something from what I remember. xD
