When the show began utilizing computers, the cardboard cutouts were scanned and re-drawn with CorelDRAW, then imported into PowerAnimator, which was used with SGI workstations to animate the characters.[46][48] The workstations were linked to a 54-processor render farm that could render 10 to 15 shots an hour.[46] Beginning with season five, the animators employed the same method, instead using Adobe Photoshop and Adobe Illustrator to design new characters and objects, and Maya to animate them.
