In the episode titled "Super Agent 2" Season 2 Episode 3, the ruler Senkah the Shamer bares some interesting resemblance to the witch Yubaba/(Yubaaba) from the Studio Ghibli/Disney film Spirited Away. They both possess a shorter than average stature (relevant to other characters), have an over-sized head, are heavy smokers, are somewhat elderly in appearance, use a long cigarette holder, have a raspy voice, have long bell-shaped dresses, and are both oppressive rulers.
