Explore Every Part of Each Site

Along with finding collectibles and clearing stages, you must also explore every inch of each site to fill out the map. Since there are certain parts of each map that cannot be easily reached, we recommend inking every part of the stage to compensate.

How to Check Areas of Interest

Use Smalfry to Search For Items

Areas of Interest are the green areas found on each site's map. Exploring these areas with Smallfry will allow you to find any of the hidden collectibles remaining in each site, so take time to explore each section when you can.

How to Use Smallfry

Ink Areas to Uncover Hidden Items

Although Smallfry will guide you to the general area of a hidden collectible, there are times where you will have to ink the surrounding area to pinpoint the exact location. Make sure to ink ground near Smallfry whenever you can't immediately find the hidden collectible.
