What is the golden block for?

[hushed agate]

And how can I use it, when I put it on the map it dissapear (Golden Strawberrie unlocked)

[fathom cliff]

You need to be holding the golden strawberry

It'll pop up when you get close to the block

[tough storm]

to be more specific, you have to actually enter the room while holding a golden

you can't just put a golden (or use give_golden) in the same room, the blocks won't show up
