User blog comment:Marceline the Moshling Princess/Disney & Pixar are probably still trying to complete the costumes!/@comment-4835804-20130610103300/@comment-11203388-20130619233747

The costumes look pretty hard to animate. Lets say you work at CP. They told you to animate a costume that looks like it has 2 heads. Your boss also told you to make a costume with two giant legs sticking out.

'SOUNDS. PRETTY. HARD.'
