What was your favourite childhood cartoon? Mine was definitely Phineas and Verb. I used to watch that every day coming home from school and I'm pretty sure I've watched every episode of it.

My favorite childhood cartoon was Bugs Bunny I loved how mischievous he was and how he was a troublemaker and how he terrorized Elmer Fudd whatever his name was so Bugs Bunny

Like Tom and Jerry

I don't know if this counts more as anime rather than cartoon but I would say Sailor Moon was my favourite.
