What Does This Hopper Take?

I know this easter egg has been found.
So I'm just wondering what does this hopper take if anything?

Searching for Jumla's secret, I see.
What all have you tried throwing in?

 

Mashed insect and emerald also rotten flesh I think.
Plus I did say it was already found.

 

Try an EB.
Also yes, ik. I just misread it and edited my post, but you must've started replying before I edited.

 

I Also threw a gateway island map for no reason :P
and an EB @DirtyDoge

 

This is from an abandoned dungeon(?) idea I believe. I forget who exactly was the one who made it though :/
Honestly don't remember too much about it, but it was found long before even Gavel. Plus, people have already been inside when it was first discovered and I don't believe there's anything there.

 

Bump. So the hopper just leads to nothing/doesn't work?

 

Try to drop @SizzlingBacon
huehuehue
