Trees (Shrek)

The Trees are minor characters in Shrek 2 and the supporting villains (redeems at the end) in Shrek the Third. They are voiced by Andrew Birch and Christopher Knights.

Ability
The Trees can disguise themselves as ordinary trees and they also use their leaves as a parachute.

Shrek 2
In the Poison Apple Inn, they are arm wrestling and one of the tree's arm breaks.

Shrek the Third
Prince Charming walks into the Poison Apple Inn and put his cape on one of the Tree's branch, which the tree angrily puts the cape down on the floor. Prince Charming persuade the Trees and the other villains to join his side to rule Far Far Away. At the island, the Trees, Captain Hook and the Pirates ambushes Shrek and his friends and tries to kill them all (excepted Shrek that is wanted captured alive). Shrek defeated the villains when they runs away from this. At the musical stage, some of the two Trees revealed their names, Steve and Ed, and the trees and the other villains turned against Prince Charming and learns that being treated like losers doesn't mean they are one.

Trivia

 * The Trees are possibly from The Wizard of Oz.
