For me Dr. Seuss wasn’t a big part of my childhood. Not that strange considering I grew up in The Netherlands and English is a foreign language for us. Which means that his materials aren’t as widely spread here as they are in the United States.
You do come across Dutch translations of his books and of course the odd movie from the United States. But that’s just noise compared to Dik Trom, Puk van de Petteflet or Kruistocht in Spijkerbroek. Now those are big and recognizable parts of my childhood (yeah I’m old, shush).
