Mor' Otesi is a planet filled with purple crystals. Its landscape is now barren and rocky and its original native inhabitants largely became extinct. However, one particular species adapted to the perilously high levels of electromagnetic radiation and has managed to thrive here over the millennia despite the planet's seemingly inhospitable atmosphere: Crystalsapiens evolved unique attributes to take advantage of their irradiated environment and went on to create a complex and sophisticated society on modern Mor' Otesi.
1. After Max informs you of Echo Echo's Sonic Scream, there will be another glass crystal in the corner. Use Echo Echo's Sonic Scream or his Wall of Sound to shatter the glass and retrieve the Plumber Badge.
