Production
The first special used the style of animation that both Alan & Adian and ChalkZone used. It was very challenging to animate Rudy Tabootie in the style Alan & Adian used. However, it was no problem animating Alan, Adian, and later on in special 3, their friends in ChalkZone form, according to ChalkZone Character Desingers Greg Emison, Bernie Petterson, and Pat Ventura.
