Purple Chu can be found in the Lakebed Temple, Hyrule Field, Snowpeak Ruins, and Caves. Purple Chu are the result of a Red Chu, Yellow Chu, and Blue Chu merging together. When Link attacks a giant Purple Chu with his sword, it will split into multiple smaller ones. When defeated, they drop Purple Chu Jelly, which Link can collect in an Empty Bottle. Drinking it will have a random effect on Link’s Life Gauge.
