Wreck of the Admiral - does the mysterious chest ever open or is it just decorat

I've never found anything to open the Ornate Steamer Trunk in Wreck of the Admiral. In searching for an answer, it appears that this item has inventory disabled so it will never be opened. The message does state that even if you had a key, it would not open. So, I think it's just flavor text - a joke from the devs. You can sell it for $5000 simoleans, so I guess that's your treasure 🙂

You are probably right. A pity, a little puzzle would have been nicer than a joke.
