[Rando Suggestion] Shuffle requirements to unlock certain areas

The ones that come to mind right now are Sleeping Waterfall and Jabu-Jabu's Belly.
Jabu-Jabu, for instance, could be unlocked by playing a random Ocarina song, offering it a random collectible like a bomb or Deku Stick, or a random bottled item besides a fish.
Sleeping Waterfall could be unlocked by playing a random song besides ZL.

There might be other areas that can have randomized requirements (e.g. Deku Tree, Kakariko Gate, Mido blocking the way to the Forest Temple, Ruto's Letter, the Shadow Temple entrance, the song to play to move the ship etc.)
