Not Caving Under Pressure!

S21, E37: On their way to the ferry back to Melemele Island, our heroes take a shortcut through a cave. They find an area filled with luminescent moss, and Kiawe’s overexcited Marowak starts a commotion that separates everyone into groups. While the others try to find their way out, Lillie, Sophocles, and Mallow discover a group of Alolan Sandshrew in training. The Sandshrew are threatened by a Tyranitar, but Lillie intervenes. She challenges Tyranitar to a Double Battle—and wins with the help of Snowy and the Sandshrew Boss! To show their gratitude, the Sandshrew present Lillie with her very own Icium Z!
