Bluegway- item to evolve?

Looking to evolve my Bluegway but unable to find the item. Where is it from and how do i get it?

On a side note, has anyone been able to obtain a prefurred scroll? i got one (E+) from a crystal chest. So of course i want to mate for a higher grade. Thoughts?

Ancient Coral is for bluegway to pegway, I got some on expert jungle.

Thanks!

I haven't leveled past sealed (15).. is that how you unlock expert? Also is there a daily cap on how many times you can run expert?

I think bull meant expert sea, not jungle. Evo items are always found in the expert mode of the world where you got the monster's scroll. And you get 5 free attempts at vet/expert and you can buy more for good coins if you really want to play more.

I have only done 2 expert sea lvls, but you could be right, either that or was from a chest. Ive done Jungle expert many times so maybe was just forgetting. I did get a coral about 3 weeks ago from a crystal chest too.
