Parodies of anime with heavy themes feature the characters in chibi form. Each episode is broken down into segments.

Both are comedic counterpart series to their respective parent series and have short episodes (approx. 5 mins) consisting of non-stop gags based on a "toon"/"chibi" style of animation.
