I love it that after so many years I’m playing this cartoon for my kids. I watched it in Poland very often

This was my first introduction to the Once Upon A Time... series as a kid.

greetings from preparation to immunology exam :D

I used to watch these as a kid and developed an interest in science so nostalgic

「あのねあのね！」

Seeing a White Blood Cell cop tower over the camera with a displeased look on his face made me realize that the White Blood Cell cops must seem intimidating to Bacteria and Viruses, I know I'd be if I were either pathogen and would see them as scary predators that want to eat me.

there was one more cartoon similar to this which used to air on Cartoon Network in India but I don't remember the name. If anyone can help?

The music was good too.

Is the Megacomputer a thing that happened in "Once upon a time...Space"....or did they just mention that as if it's something we should already know about and never actually did anything with it ?
