This page offers a guide on Shadow Mario in the Park, which is the 7th episode in Pianta Village.
Spray Shadow Mario
In this episode, you’ll need to chase Shadow Mario around and spray him using the spray nozzle on your FLUDD pack. Shadow Mario will run quite fast in this episode and will perform a lot of fancy jumps in an attempt to get away from you. Your goal is to just keep up with him and spray him with water wherever possible. He will run around the entire map, so make sure you’re ready to perform some fast jumps to keep up with him! He also now leaves damaging graffiti goo behind him so you’ll need to watch out for that!
Luckily though, there’s no time limit in this episode, so you can take as long as you need to spray him with the necessary amount of water needed to defeat him in this level. The Shine Sprite will spawn once you’ve defeated him.
