All Aboard the Zeppelin: Chapter 7

Begin by completing sidequests to increase your citizen count. In Evermore, there are three new sidequests: "Tyran 4 Evermore" (090), "New Model Armor" (093), and "Seeking Superior Weapons" (094).

Travel to Goldpaw to accept another sidequest.

In Hydropolis, accept three more sidequests.

Check Swift Solutions in any city for new sidequests.

Broadleaf has 11 sidequests available.

Accept the sidequest "The Search for Eternal Youth" (080) in Greenglade Cave, located west of the Forest of Niall, up the mushrooms.

After completing available sidequests, return to Evermore to find more. These include "Daphne, Glaucus’s Biggest Fan" (069), "Sense and Sensibilities" (070), "Thetis, Medical Merperson" (071), "Chip the Child Prodigy" (072), "Oz Wants Out" (073), "Price’s Delayed Delivery" (074), "Kent, the Magical Ore Analyst" (075), "An Upgrade for Andy" (076), "Kimmy, the Cool-Headed Cop" (077), "Bot on the Run" (078), "Candy, the Spirit-Seeker" (079), "Brodie’s Last Big Job" (081), "Rumpel, the Village Vet" (082), "Lady Forget-a-Lot" (083), "Head-to-Head in Hydropolis" (084), "Green Fingers, Idle Hands" (085), "Bulking Up Batu-Style!" (086), "Do You Believe in Higgledies?" (087), "A Matter of Taste" (088), "At the Cutting Edge" (089), "The Great Higgledy Hunt" (091), and "Big Unveiling in Broadleaf" (092).

With over 50 citizens, upgrade your kingdom to Level 3. Focus on upgrading resource gathering facilities first, as their materials are needed for new equipment and some sidequests. Upgrade the Institute of Innovation, Barracks, Training Ground, Explorer’s Guild, Hubble-Bubblery, and Dimensional Lab. You can also level up Outfitters and Weapon Workshops.

Once kingdom upgrades are complete, exit Evermore and interact with the airshop to begin modifications for your airship.

After Bracken finishes, you will obtain your airship. You can board it with the Triangle button and land with the X button.

To progress the story, bring Zip back home to Broadleaf. Landing anywhere near the city will suffice.
