Anime — Hakaba Kitarou

Graveyard Kitarou, with his Dennis-the-Menace striped output, and a walking eyeball for a father are part of the Japanese popular culture rather like the Addams family in the USAn influenced West. This season from Q1 this year (the only one of that season I followed, and the slowest-subbed one to boot) is but the most recent remake.

Set in c 1960 Japan, it's quirky schlock-horror, slightly reliant on fart-gags whenever the noxious Rat-man is involved (though once to amusing effect when a vampire has sunk its teeth into one scrawny buttock).

The OP pretty much summarises the series, and has damn catchy tune in "Mononoke Dance".
