»[Skyblock] Impossible challenge?

IGN: mathwhizkid
Heres my conern: Currently I'm not sure if you can summon the dragon in the end which one of these challenges requires a dragon egg
The center of the end is protected so I wanna know why we cant just resummons it with 4 crystals.
EDIT: I learned from a player that someone had it but was stolen

 

You can re summon it, but the egg drops only once, so its not of great use.

 

There is 1 egg in existance, but i do not know who has it.

 

I had the egg, but i lost it, now nobody knows who has it, i think.

 

I did hear some staff saying they had it, but I don't know what happened to it after that

 

Lol, u lost the egg, and im sitting here wondering how I dont forget every piece of wheat I put in the chests...

 

I sold the egg to bluepyth and he owns it for now so u can talk with him
