Epic Mickey 2: The Power of Two

This trophy is what makes the Platinum so complicated, because much can go wrong and the auto-save can't be disabled so you need to play a completely methodical and obsessive game to achieve this. There are 20 quests and are as follows:

• A Captain's Life For Me
• A Friend in Deed
• Clothes Make the Splatter
• Creative Threedom
• Donald's Date
• Finding the Hidden Heroes
• Goofy's Fountain Mishap
• Horace's Assistant Assistance
• Much Ado About Blotlings
• One Toon's Trash
• Operation Gremlin Drop
• Out of Toon
• Rebuilding Autotopia
• Thanks for the Memories
• The Bunny Wranglers
• The Encyclopedia Wastelandica
• The Other Side of the Screen
• The Spirit of Wasteland
• The Wasteland Limited
• Watch the Skies
