Achieving 100% completion in Captain Toad: Treasure Tracker requires more than just finishing all levels. You'll need to collect every single Super Gem in every level, complete all bonus objectives, find all Pixel Toads, and finish all bonus levels. To track your progress, check the level selection screen; a gold crown indicates all Super Gems are found, and a stamp signifies the bonus objective is complete. For Pixel Toads, a small Pixel Toad icon will appear. Revisit levels where you're missing collectibles. Sometimes, a new power-up unlocked later in the game might make a previously difficult collectible accessible. Don't be afraid to replay levels multiple times, experimenting with different approaches and camera angles to uncover every last secret.
