How This Guide Works
Each world card leads to a dedicated route page. World guides group normal course clears, Wonder Effects, secret exits, Badge Challenges, Search Parties, shops and other one-seed activities without turning this hub into one enormous checklist.

How Wonder Seeds Work
Most standard courses award one seed for reaching the normal goal and another for completing the Wonder Effect. A course with a secret exit can contain a third seed. Badge Challenges, Search Parties, Break Time stages, races, arenas and similar activities usually award one seed.
Completing every Wonder Seed in the game awards one of the six save-file medals. Royal Seeds are separate world-clear rewards and are not included in the 225-seed total.
