I was 6 years old when I was able to play OoT and get somewhat far. I probably would have beat the game too but my control sticks started to wear down on my controllers. I didn't beat OoT or MM until I got the Zelda Collector's Edition on Gamecube. Anyway, playing the game that young, sometimes I had weird explanations of things I saw in the game. For example, I had a weird thought that Jabu Jabu was constipated. I understood you were inside him, so I thought that section way in the back was basically his intestines. Those weird things you have to hit with your boomerang until they fall off, I thought was poop. Now of course the in game reality is those things are extensions of Barinade, I didn't piece together a connection for some reason when I was young. So Jabu Jabu is infected with parasites, those things aren't poop, but maybe I wasn't wrong about that area being his intestines? Let's take a look at the dungeon map for Inside Jabu Jabu's Belly. The furthest area in the back happens to be where you fight those parasetic tentacles, since the area is so far back I felt it'd be the closest area to his anus. The English title description for Barinade simply calls him a Bio-electric Anemone. But the Japanese title, translated to English, actually calls him an intestinal parasite. So Barinade's tentacles are expanding out into Jabu Jabu's intestines, which is most likely that back area in my opinion. I'm posting this in the theory section because I also wanted to point out, even after Barinade is defeated, those smaller parasites, Baris, remain. The holes in Jabu Jabu's stomach as damage from Barinade also don't go away. And in the Adult era what we find is Jabu Jabu is no longer in the domain. I think the damage Barinade caused was so severe that Jabu Jabu died. I have to give @Magic Bean Seller a menetion. I posted this late so it slipped my mind to add this in. It was from him and I talking about OoT last night that I got the idea to write this.
