Talking Trees

The  are two sentient trees who appeared in "A Lemony Lesson". Nickel finds the two trees and kicks one, causing the two to yell at him. The other one comments that he is an apple tree, and therefore, can be ignored because the challenge involves lemon trees. Lightbulb is quick to acknowledge that the trees were not there previously (three seconds ago), and MePhone4 notes that she is correct, but focuses the attention on a different set of trees that do not talk.
