Retrieving the Small Wooden Box
Lieutenant Snibug has the small wooden box, says Vittorio, and it's crucial that you get that box back. You'll find Snibug north east of Sergeant Cargug, just outside the Tanglewood Fort. The Lieutenant will inform you that the box is already in Darkthorn's possession, but he may pull some strings for you - if you help him first. Agree, and Lieutenant Snibug will give you the quest There's Fungus Among Us.
Briarwood is apparently a dangerous place - if you couldn't tell by looking around. Snibug asks you to go to the Mushroom Cavern and defeat 15 Fungus Golems.
Head north and you'll find the cavern. This is a medium length instance with lots of enemies to fight, so be prepared for a bit of a battle. When you're done, return to Lieutenant Snibug. You have another task to complete, and Snibug will give you the quest It's Business Time.
Lieutenant Snibug wants your help defeating Amaranthus, an old and dangerous floren. You can find Amaranthus in the Bristlewood Glade, along the northwest edge of Briarwood. This is a medium instance, and once you're done, Snibug will have one more task for you in the form of the quest Pampered Pets.
You need to pick up the gifts for Darkthorne's pets. Visit the following pet supply NPCs:
- Florina in Sanctuary, west of the Warpstone
- Jennifer in Crossroads, north east of the Warpstone
- Bowawow in Highroad Junction, north of the Warpstone
- Twiggi Truespirit in Shrouded Glade, west of the Warpstone
When you're all done, Snibug will agree to let you through, and suggests you can get the box back if you talk to Captain Chugug.
Captain Chugug is up at the Briarwood Palace, on the other side of Tanglewood Fort. If you haven't been through yet and don't have the Briarheart warpstone unlocked, you'll have to go through the Tanglewood Fort instance first - alternatively, you can have someone give you a friendly teleport to the other side. No matter how you get there, Captain Chugug is right by the warpstone. He seems happy to help, and gives you the box - empty. Well, Vittorio never said explicitly we needed the contents of the box, right? Return to Vittorio, and he seems really worried. Not just worried, he's going to force you to go back and tell Geoffery the news - and also lets you know that his caravan isn't a bunch of merchants, they were planning sabatoge and assassination!
