item code name

Hi so I need and eel for the community center and I was wondering if there is an item code for it. I’ve looked it up and google said “The item code for an eel is .” :(

I was almost done with the "Strong Stuff" quest when I noticed some of the Potato juice went missing (must have sold them through the bin by mistake). What's the item code of "Potato juice"? So I can cheat my way back to completing this.

I don’t know if I’m messing something up but when I try to do the item code name at the shrine the brackets don’t pop up, it was in the patch notes so I feel we should have it but idk hopefully bug and not that we can’t use it🥺
