Also nice read: animationineurope.eu
For Hungary there is also the Mézga family, Szaffi, the King Matthias series and Magyar Népmesék, also Ludas Matyi
Wow seems like Hungary has a lot to explore
A Mézga család / The Mézga Family is actually three separate series, the original one is about an ordinary 80s Hungarian family with a genius son who invents a time-telephone that they use to talk to their great-great-great-son. They ask him to send things back in time to help with their problems, but they inevitably use them wrong, and chaos ensues.
There are two spinoffs, one which is about the same genius son making an inflatable spaceship and going on adventures in space with the family dog, and one where the whole family goes on a trip around the world.
Szaffi / The Treasure of Swamp Castle is an animated movie set in 18th century Hungary, the story based on a novel The Gypsy Baron. It's a cute and charming romance story. There is an English dub since it was made as a Canadian collab.
Mesék Mátyás királyról / Tales of King Matthias is a series about King Matthias (1458-1490), revered in Hungary as the "just king", going incognito in his kingdom and righting wrongs.
Magyar népmesék / Hungarian Folk Tales is another series, with each episode being an adaptation of a Hungarian folk tale. Fun fact, the series does not shy away from animated female full frontal nudity despite being from the 80s.
Ludas Matyi - the title being the name of the protagonist - is the adaptation of a popular story about a young shepherd vowing revenge being caned by the local landlord for insubordination - the landlord stole his geese. He says he will return the favour threefold, and accomplishes his goal with guile, beating up the landlord three times.
Sounds really entertaining. Especially the time telefone :)
