Trome sap was a viscous liquid exclusively harvested from the renowned Trome tree located on the Forest Moon of Endor. Due to its incorporation into various concoctions, the sap was considered extremely valuable. It served as a key component in the remedy for plant growth formula. During the events of the stranglethorn crisis, Wicket Wystri Warrick and Kneesaa a Jari Kintaka, two Ewoks, embarked on an adventure to procure Trome sap from the Trome tree. Their goal was to halt the rampant spread of a massive stranglethorn. It became apparent that the harvesting process necessitated severing a branch from the Trome tree. This presented a challenge, as only a single branch remained on the Trome tree when the Ewoks reached it. Because removing the tree's final branch would result in its death, the two Ewoks ultimately chose to forgo acquiring the sap, prioritizing the preservation of the tree, which also served as a habitat for the Tromes.
