Noki Bay - Episode 1: Uncork the Waterfall: Follow floating platforms to half-clams, then to a scale. Jump on the platform, spray water into the jar to rise, or backflip to the ledge. Wash off pirate ship and squid-shaped goop to create platforms. Jump across platforms, wash off wave-shaped goop for a small platform, then jump to the pirate ship platform and onward. Wash off dolphin-shaped goop, use the scale platform and jar to lift yourself, then hop to the dolphin platform and larger ledges. Wash off whale-shaped goop if desired. Run up the hill, wash off octopus-shaped goop at the top to create a wall-jumping platform. Wait for a gap in goop balls, then wall jump to the top. Wash off the goop shape to the right, jump onto the platform, then to a ledge with a Noki and a spring. Hover to a ledge with a 1-up. Jump and hover to the ledge near the cannon. Wash goop off the ground. Defeat Monty Mole by spraying his Bob-ombs, picking them up, and throwing them at him twice. The waterfall cork will explode, revealing a shine.

Noki Bay - Episode 2: The Boss of Tricky Ruins: Follow floating platforms behind the younger Noki. Talk to the old Noki, who reveals a shine and explains that spraying brown squares on walls creates paths. Spray the first brown square high above the old Noki to reveal a wall-jumping maze. Navigate the maze by wall jumping, turning right, and continuing. Upon exiting, defeat three Bloopers. Spray the nearby brown square to reveal another maze. Wall jump to the top, fall down, use the small wall-jumping section, then the long wall-jumping section to reach a high point. Defeat three more Bloopers and the Gooper Blooper. To defeat it, spray its face twice, pull off its tentacles (optional), pull its pacifier, and repeat once.
