Things they don't tell you about Ocarina of Time part 2

More observations from the Legend of Zelda game they don't tell you in strategy guides.  At least, the ones I've found:

*You aren't supposed to follow Princess Ruto when she swims up up and away from you once you know how to play the flute by the Triforce symbol.  That's it.
*Lighting those torches by the waterfall in Zora's ice cavern doesn't do anything.
*You can cut past Zelda when the castle is collapsing, but you still have to kill two skeletons and a zombie really fast.
*The zombie is near the exit.  You can't use the sun song to stun it.
*You can't buy the shield in Dodongo's cave or buy the kid's blue and red vests once you have the adult versions.  Maybe not even before then.
*A video walkthrough of the game is sometimes better than a strategy guide, especially at a boss fight.
*Enemies allow a fair amount of time for aiming arrows.
*Bongo Bongo: You cannot shoot his fist, only his open hands.  Nothing can stop the fist.
*Octopus can only be hurt from the rear.  Stun from the front.
*Princess Ruto can teleport.  She can't be lost forever or killed inside that big organic maze thing.
