I have a small idea for the end if an end update comes out relatively soon. I would like to suggest a sort of end mould, Shulkellium. Don't have too much to say about it but would love to see it implemented in an end update.
I also have an idea for a sort of flower/bush that would bear fruit called Shulkorn. There would be the Shulkorn Shrub (the actual plant) and Shulkorn (the fruit) I thought that the Shulkorn could levitate you 2-4 blocks after you consumed it.
Not 100% sure about my textures but hope you guys at Mojang see this!
