What even is this?

So a few years ago i had this worldbox save and played in it for a long time. But a fee months/weeks after playing the save i looked on this island and there was a potato/coin guy on it. I still wonder what that was cause i was playing on mobile so the game wasn’t modded. I can provide a photo you might see it looks like the iconic worldbox guy. I don’t have the exact photo cause i didn’t care the minute i saw it. The thing isn’t in my save anymore idk where it went but i hope this is enough for you
