Eye of Ender

Is there any use for them after I've found the portal and have a few Ender Chests? I have 15 extra and 3 Ender chests, but I'm thinking of making 2 more. So is there any use for 13 Eye of Ender?

I thought you were removed and bothering me already when I found ender eyes

Does anyone really know where the Ender Pearls come from? Not really. All we can really do is speculate. And that's what I'm doing. I think that Ender Pearls come from Shulkers. But how can Shulkers have Ender Pearls, you ask? I mean, they don't drop Ender Pearls when you kill them. Well, that's because Ender Pearls are the fossilized remains of long-dead Shulkers. Well, first, let's look at the Eyes Of Ender that you need to open the End Portal. They're about the same size as a Shulker without the shell. And what's one of the ingredients to craft Eyes Of Ender? Ender Pearls. Also, when you throw them, you teleport to wherever it lands. Shulkers can also teleport. It's possible that they kept this power throughout the fossilization process. It's also possible that some sort of blue liquid coated the dead Sulkers somehow and hardened, which is why Ender Pearls look like that, and it also explains why the Shulker doesn't just decay and leave behind only the shell. How the blue liquid got the dead Shulkers in the first place? I'll have to do a bit more thinking on that. But why do some Endermen carry them around? I dunno. Maybe for good luck? They can't be using them for their teleportation qualities, as not all Endermen have them, yet all Endermen can teleport. Maybe to study them? To make Eyes Of Ender to get back home? This definitely requires a bit more speculating, but I may reach a conclusion. Maybe one day (hopefully soon), MatPat will touch on the Ender Pearls a little bit in a Mini Theory or something. But for now, this is my headcanon. Maybe you can comment some way to fill in the holes or even your own speculations on what the Ender Pearls actually are. I know I'm not the cleverest, and this is just speculation. Idk. Maybe your speculations will make a bit more sense.
