They are two talking trees who speak in a Cockney accent.
Steve and Ed were seen in the Poison Apple having an arm wrestle challenge, and one of the trees' arm breaks off.
Prince Charming walks into the Poison Apple and asks Steve and Ed (and other villains) to join him so they can take over Far Far Away. Charming also wants to murder Shrek as revenge for killing his mother the Fairy Godmother.
Steve and Ed are later seen guarding an entryway, both equipped with bayonets. At the climax, Steve and Ed grab Charming and reveal their names.
- They might be based on the trees from The Wizard of Oz.
- In Shrek 2, Steve's and Ed's eyes glow red, but for unknown reasons in the third film, their eyes do not glow.
