There's one brief scene of a mental institution in the Christmas special (season 2, episode 0) with the patients wearing straitjackets. (minutes 27:50-27:56).
in the music video for the song "tangananica, tangananá" , right at the end when the guarennes brothers are cleaning up after the mess they made , theres a lot of gross slurpy eaty licky sounds ! these only show up in episodes where this song is first place (so episodes 3 and 21 of season 1)
Played with in S4; Mario Hugo gets a noose intending to commit suicide but instead of placing it around his neck he sits on it and uses it as a swing "so he will be swinging on it till he dies out of boredom".
not actual cannibalism, but in the song "huerfadrino" there is a character wearing hannibal lecter's mask while assuming that the singer's godfather was turned into his dinner. right after that, the singer implies that another cannibal ate him.
theres like a whole bunch of screaming in "el fantasma del estudio" , both in juan carlos's green note and as a running gag (the episode at first focuses on the crew trying to find the source of a scream , which has different sources but sounds the same everytime)
In one of the episodes bodoque says "que te pasa vieja conchetumare" to a girl, wich translates roughly to "what do you want you old m**********r the curse word is cut short though
one example i can recall is the music video for "dracula, caligula, tarantula" , so watch out on season 4, particularily the episodes where it gets first place in the ranking top
The show contains caricatures of black people, Asian people, and/or native people in the instances it chooses to show "human" puppets; one of the biggest offenders being season 2 episode 04 "Japonés" which contains a LOT of racism against Asian people in-general.
The show also contains LGBT+phobic jokes.
(Note: While, yes, there is a cultural gap between racial and LGBT issues in Latine countries and English-speaking countries, mainly the US, and that pre-2010s humor scene in Latine countries ran on being at least slightly offensive; it does NOT excuse this content.)
