Latest update also introduced further configurations to Varrock's museum.
There's an easter egg hidden in there as well. It's not that special but it's a nice, small fine detail. You will notice it when you trigger it.
First one to find this will win 1x Member ticket and 1x Double XP Scroll.
As a hint I'd say look at the cases and what items are in them. This easter egg can be triggered by doing a certain action, it may or may not require certain items as well.
There's also Pirates of the Caribbean reference hidden to one of the cases. There's no reward for finding this but post here if you found it.
I do not expect this to be an exciting event or interesting at all to many people and therefore there is no deadline. I will post another hint tomorrow in case nobody has found it.
Good luck.
Ps. Staff, Jandar & Eryn are excluded due to them being able to review the script.
