Mocking Tree

"...silver, longitudinal beings who wavered on two points and spoke in a high-pitched gibberish that reminded us of Mocking Trees."

- Etro and Droza Edthatt

Mocking Trees were a type of tree. When Etro and Droza Edthatt heard Humans speaking in Galactic Basic Standard, they were reminded of Mocking Trees.
