Things I just found out:
1. Miyamoto thinks of Mario characters as actors.
2. Mario and Peach's height difference is super inconsistent.
3. Elsa is kinda similar to Rosalina. (and Rosa had a track called "Rosalina's Ice World", which came out years before Elsa so I'm assuming Disney was inspired by Rosa or something like that.
4. American Greetings made both the Care Bears and Strawberry Shortcake. Both franchises began with an appearance on a greeting card.
5. Robbie from Care Bears: Unlock the Magic is a male in the Spanish dub. (she is female in English but the weird thing is that her original design was kept (not that I would expect the producers to change her design to remove her eyelashes (female characters in UtM have eyelashes) but it's weird how instead of keeping her female they swapped her gender instead. (probably because of her name))
