 The character Gromble, in particular, bears a close resemblance to the Blue Meanie characters from that film.Director of the series Igor Kovalyov said the style was inspired by his earlier Soviet film "Investigation Held by Kolobki" which he and Gábor Csupó showed to the producers who then gave Kovalyov's team a lot of creative freedom with the art direction and storyboarding.Csupó said some elements of the show have a look similar to the film noir genre, and called the city dump where the monster characters reside reminiscent of the visual style from the films "Blade Runner" (1982) and "Brazil" (1985).
