What each player can do here
- All four heroes move the same way; only their animations and sounds differ, so pick whoever you like.
- Team moves only work with a partner: leapfrog over each other for a longer jump, drop a rope from a ledge for the other to climb, and hug to add a heart for both of you (Gamereactor calls that heart temporary).
If your skill levels differ: No seat is harder than another. Each player sets their own starting hearts, so a newer player can take three (or the infinite-health setting) while the other takes fewer.Our suggestionThe surer player goes up first and drops a rope, and you hug whenever one of you is low. How to split the roles
What's That Sound?
Part 1 of 5. Follow the picnic signs and meet Toku.
- BothHead right after the picnic signs; this first stretch teaches hopping over enemies and using bounce pads.single source
- BothToku, who leads the Hokuns, asks you to recover three stolen tomes and teaches you the spell that turns a beaten thief to stone.
A Lead … Kinda
Part 2 of 5. Get a way across the gap toward Terrarium Town.
- BothMazzy, a pink alligator who builds gadgets, gives everyone Boost Jump: a second jump at the top of the first.
- BothGo back and boost across the gap heading west. The main quest is always the red Mickey flag on your map.single source
- BothMoon Juice is safe to float on; you can swim across its surface.single source
Things Are Looking Up
Part 3 of 5. Find a way up to Terrarium Town.
- BothLocked doors on Monoth each need three keys, usually tucked down the paths nearby.
- BothIn the Quarry, Mazzy hands out Wall Jump: cling to a wall for a moment and kick off it to climb.
- BothA Healing Pool refills every lost heart; the signposts point to them.
- BothAt the Terrarium Town Gates, Dex sends you to find his Uncle Steve through the Service Tunnels in Gizmopolis.
I'll Be a Smuggler's Uncle
Part 4 of 5. Track down Uncle Steve and the first thief.
- BothIn Gizmopolis, hop on any bell that looks like a shop counter bell: it moves the platforms nearby.single source
- BothA cutscene drops the four into a deep pit where Thief #1 is waiting.single source
Thief #1 (boss)
Part 5 of 5. Drop things on the thief's head by bouncing off switches.
- BothYou never hit the thief yourself. Wall Jump up to the yellow switches on the back wall; each one bounces you higher, toward the next.
- BothHit every switch and something heavy falls on the thief. Each round adds spikes and falling hazards, then the arena changes.
- BothIn the last phase the switches blink in and out over conveyor belts: take them one or two at a time instead of chaining them.
- BothCast the spell to turn the thief to stone and take the Tome of Engineering.
Boss
PostOfficer (Thief #1)The first tome thief
- Phase 1: Six yellow switches, three on each side. Lighting all of them drops a capsule on the thief; spiked hazards and falling blades are added each round.
- Phase 2: A gate drops, the layout changes and conveyor belts appear. The job is still the switches, around more spikes.
- Phase 3: Only conveyor belts remain, and the switches pop in and out of the wall, so wait for each one to show.
- Touching the thief does not hurt you, so you can pass straight through it on the way to a switch.
- TheGamer counts eight switches in the last phase and notes that a switch stays down once hit.
Extras and notes
- Glimt comes in clusters of three. Spend it on the Glimt reward panels: each finished picture adds a heart.
- Mickey Memorabilia comes in 23 themed sets of three pieces, often in hidden rooms behind a wall with a small chip in it.
