He is the Great Fi-Fi-Fi Fisherman’s Main Worm, therefore his location at the riverside is more than logical!
In the ’80s, the writer of the tale, István Csukás, decided to write a piece for children about a Fisherman, who loves to fish, and always gets into interesting adventures.
He asked a famous drawer, Ferenc Sajdik, to draw the pictures for his tale.
When Sajdik read the first draft, he ran to see Csukás, and outrageously asked him:
“It is a story for children???”
“Yes, that’s right!”- said Csukás.
“And you want to make these children laugh, or cry?” – insisted Sajdik.
Csukás, who was a very famous and admired tale-teller, asked back in surprise:
“But why would they cry?”
“Because your tale starts WITH A WORM PULLED ON A BIG HOOK BY HIS BELLY, that’s why!!!” – cried Sajdik, and immediately drew up a better idea: a life belt around the little belly of the Worm.
Like this, the Worm, aka the Main Worm, (Főkukac,) transformed from a simple tool to a very good friend of the Fisherman, and we, the Hungarian children followed their adventures for many-many years.
I don’t know if the story is true, but I like it, and I think if you have a opportunity to see the Main Worm, you should not miss.
