Old Trunk Treasure is one of the new additions to World of Warcraft: Dragonflight in Patch 10.1, Embers of Neltharion. While there’s a ton of new stuff to do — a new faction, a new raid, and a new zone — there’s also more loot to find. Knowing how to open the Old Trunk Treasure isn’t as simple as walking up to it and unlatching the lid. Here’s what you need to do.

Where to Find the Old Trunk Treasure in WoW Dragonflight

To open the Old Trunk Treasure, you’ll first have to find it inside a stone cart in Glimmerogg, located in the southernmost part of Zaralek Cavern.

Unfortunately, the chest is locked. To open it, you’ll need a key, which is being held by an absolutely adorable Thieving Rock Mouse. The Mouse will run and hide in a total of five locations while you track him down. Here are his hiding spots.

Thieving Mouse Location 1

You’ll first find the mouse just to the right of the cart, in the purple bush.

Mouse Location 2

After you find him here, our shy little friend will run away. Follow him up the path behind you to find him at the upper right side of the path, hiding in a little basket to the right of a big stone door. Click on him again, and he’ll run away again.

Mouse Location 3

Follow him down the path to the right. There, you’ll see a couple of Niffen and a Strongarm sitting around a stone table. You’ll find the mouse hiding behind the stone table. Click on him again, and he’ll run away again. Curse you, you adorable thieving mouse!

Mouse Location 4

Follow him down the path. You’ll see another stone cart full of mushrooms and straw almost directly across from the stone cart housing the Old Trunk Treasure. Our thief is hiding here.

Mouse Location 5

To find our thieving mouse this time, you’ll need to climb a little bit. The mouse has run up the southernmost tower and parked himself on one of the balconies. Follow him up there. Once you catch him, he’ll finally give up the Old Trunk Key. Take your shiny new key down to the Old Trunk, and you’ll be able to open it at last.
