Encounter of the plant kind. 

"The jelly geode is an edible mineral formation found naturally occurring in cave systems and mines. While it outwardly resembles an inedible geode, jelly geode can be consumed in entirety. Jelly geodes come in many flavors. Many creatures see jelly geodes as a delicious food source, and there are no known species to whom they are toxic."
