Go to the scene when Juni asks his little robotic bug friend, Ralph, to spy on Gary and Gerti Giggles to hear about their new mission.

On the way to the breifing room, Rlaph crawls along a wall and jumps onto some sort of rail with vertical bars. Ralph clearly lands on the THIRD bar and stops. When the camera goes back to Ralph, it shows him clinging on the FIRST bar.

Either his grappling hook got stuck on something and yanked him back, or the computer guys that do Ralph were to lazy to make sure the laws of physics still apply.
