The World Exploration Ship, previously called Merch Forge is a building that can be found in Heavenhold, which can be unlocked after clearing Archfiend Subjugation, the main quest of World 7 - Dungeon Kingdom.
By reaching the level requirement, the player will be granted to access the World Exploration, Merch Forge, Expedition, Farm, and the Monster Ranch.
World Exploration[]
The World Exploration are stages that gives Blueprint's ingredients in order to craft a Blueprint to forge into a random Merch or a random Super Costume.
It requires an Operation Plan to be able to enter a stage. It refills daily or can be easily obtained by consuming 
Princess Edicts.
Merch Forge[]
The Merch Forge is the place where the player can craft and upgrade Merch, and receive Super Costumes. Each Merch and Super Costume takes its time to craft, varying from 8 minutes to 6 hours. Once the blueprint is done, the blueprints will give the player a Merch or a Super Costume with a certain chance. There are three different rarities (Normal, Rare and Unique) varying from 1 ★ up to 3 ★★★ and can be upgraded up to 2 stars more each.
Expedition[]
Expedition is a PvE (Player versus Environment) feature, where player battles against enemies in various areas. It unlocks after the completion of Trial of the Chosen One quest in World 13. Currently, there are 4 Chosen One Areas of Expedition. Chosen One Areas are divided into Districts, with each District being divided into The Trial Areas.
Farm[]
A minigame in the World Exploration Ship, where the player can build structures using separate standalone resources (sticks, rock fragments and fishing coins), 
Gold and 
Soul Points. The player's friends are allowed to visit the player's farm (from their profiles in the friends menu).
Monster Ranch[]
Monster Ranch is a minigame adjacent to the Farm that can either be accessed directly through the World Exploration Ship, or from a bridge in the Farm gamemode. Repairing that bridge is required to access the Monster Ranch. Inside this gamemode, the player can summon monsters using Soul Points, and interact with them to collect 
Gems.
