I liked the water growing dinosaurs toys that I usually got from the capsule vending machine.
I'm a millennial, but I used to watch cartoons from the 70s and 80s.
these are more of my time though
Spoiler
Although to be honest, I even dig zoomer cartoons like Adventure Time, Regular Show, Steven Universe, The Amazing World of Gumball, Over the Garden Wall, etc. I guess I just enjoy cartoons in general. Oh and I like Anime too.
