|First appearance||"Bendless Love" (3ACV06)|
Unbendable girders have been bent in two different episodes. Bender bent one at Curvetti Bros. Bending Plant in 3002 (3ACV06) and a different Bending Unit bent two at once at the Earth Olympiad in 3004 (4ACV13).
Angle-ine: You can't bend that girder. It's unbendable!
