A Monster's Expedition achievement guide, roadmap and tracker

A Monster's Expedition is a gentle Sokoban-style puzzler: you're a friendly monster touring a museum-dotted archipelago, and you cross the water by rolling logs into bridges. There's no fail state and no timer - push a log wrong and you simply undo, so it's pure unhurried spatial thinking. About 8-15 hours to see everything.

Most achievements just mark progress as you island-hop (your first move, fast-travelling by monster post, reaching the windmill, catching the ferry home). Nothing is missable - collectibles persist and the red mailboxes let you backtrack before the finale. The two big ones are collectathons with no in-game checklist: Data Miner (read every museum exhibit) and the rare Cuddle Puddle (hug every hidden snowman), both of which realistically want a locations map.
