The Cascade Kingdom in Super Mario Odyssey serves as the first major open environment where players truly get to experiment with Cappy's full range of capture mechanics. Known for its prehistoric aesthetic and towering waterfalls, Fossil Falls contains numerous Power Moons that require clever exploration, precise platforming, and strategic captures. Gathering every moon in this area requires a mix of story progression, secret hunting, and returning after completing the main campaign.

Main Story Moons and Essential Captures

Your initial journey through the Cascade Kingdom centers around restoring power to the Odyssey by collecting essential Power Moons. Players must capture a T-Rex to smash through large boulders, opening paths to story-critical collectibles like Our First Power Moon and Multi Moon Topped with Treasure. Utilizing large captures effectively saves time and makes reaching elevated areas much simpler during your first visit.

Mastering basic captures like the Chain Chomp is equally vital for progressing through stone barricades and hitting targets across gaps. Pulling back on the Chain Chomp and aiming carefully allows you to break open glowing rock formations that hide concealed Power Moons. These early challenges teach core mechanics that become useful throughout the rest of your adventure.

Hidden Moons in Secret Warp Pipes and Sub-Areas

Beyond the main open area, Fossil Falls features several hidden warp pipes and doors that lead to isolated challenge rooms. Areas like the 8-Bit Chasm offer classic two-dimensional platforming where clever jumps reveal hidden Moons tucked away behind upper borders. Keeping a close eye on unusual wall patterns often leads directly to these retro secrets.

Other sub-areas test your timing and mastery over Cappy's motion abilities, such as the Gust Palace and rolling-ball challenges. Entering these areas requires looking behind waterfalls, under stone ledges, or using captured creatures to smash hidden entrances. Completing both the main objective and the bonus objective inside each sub-area ensures you do not leave any Power Moons behind.

Post-Game Moons and Moon Rock Unlocks

After defeating the final boss of the main story, players can return to the Cascade Kingdom to strike the local Moon Rock. Breaking this rock shatters its magical barrier, releasing a fresh batch of Power Moons across the map with new location markers. These post-game Moons are often placed in harder-to-reach locations that test advanced movement tricks.

Returning visitors will also find new NPCs, such as the Hint Toad and Koopa Freerunning team, who offer additional rewards for completing parkour races and minigames. Exploring high cliffs and deep water pools with upgraded movement abilities makes tracking down these remaining collectibles much smoother. Taking time to sweep the map systematically ensures 100% completion for the kingdom.
