Wile E. Coyote, Rocket J. Squirrel, Bullwinkle J. Moose, Boris Badenov, Natasha Fatale, Dudley Do-Right, Nell Fenwick, Hoppity Hooper, Waldo Wigglesworth, Tom Slick, Tennessee Tuxedo, Odie Cologne, Peter Potamus, Wally Gator, etc.
Here are some of the cartoons:
Ugh. That was a terrible time for Warner Brothers cartoons.
I didn’t say it was due to the way the character was portrayed. That was just what the environment was. Speedy himself is just a fast Mexican mouse.
Speedy was one of my favorite WB characters as a kid. Even then I knew he wasn’t “racist”, that is, I was smart enough to know his being Mexican didn’t mean all real Mexicans were like him. He was fast, got the cheese, and stuck it to “the man”
Western NY here from the turn of the 80s and I never heard that stereotype either. But then again maybe I lead a sheltered life because while I did hear racist jokes about other ethnicities, I didn’t get them either other than “haha they did something weird or stupid for no reason.” divorced from any pre-existing expectations.
But I’m pretty sure about not getting the Mexican=lazy stereotype. It wasn’t until a couple years ago that I heard people talking about the origins of it and that people apparently literally thought of a draped, sombrero-wearing mustachioed guy lounging under a cactus, which as far as origins of stereotypes go, struck me as more of a stereotype of a stereotype it was so heavy handed.
Didn’t realize corn chips could be used as cereal!
Don’t knock it 'till you’ve tried it.
And OK it was a silly question, if I’d thought about it.
Would now be the right time to mention that when I worked at Immigration Court, we once had training for our case management/scheduling software for which the model cases in the training manual were for Juan Valdez and Speedy Gonzalez? Yes, really.
Nah, I’d swear there were those kinds of, seemingly, weird cross-promotions back in the day.
Like my Woody Woodpecker Kazoo. What that had to do with Rice Krispies I don’t know.
How is that weird? It’s a toy based upon a (presumably) popular cartoon character. So kids will pester their parents to buy the cereal to get the toy. The cereal company increases sales, and the TV show might get more viewers. Seems perfectly reasonable from a pure marketing standpoint.
The Frito Bandito wasn’t a popular cartoon character. He was a popular commercial pitchman (for Fritos corn chips). Here, he will sing you a leetle song:
Aye -yi-yi-yi
I am the Frito Bandito
I eat Fritos Corn Chips
I love them, I do
I want Fritos Corn Chips
I get them from you
So of course the Frito Bandito eraser would be in a pack of Fritos Corn Chips. Q.E.D. 
Aye-yi-yi-yi
I am the Frito Bandito
Give me Fritos corn chips
And I’ll be your friend
The Frito Bandito
You must not offend!
So I guess this bloke is related to the Hamburglar, Chester Cheetah, Joe Camel, and Lucky C. Leprechaun?
Yup. When I read the lyrics above, I could still hear the jingle in my head; it was still being used in the early '70s, when I was a kid, and I remember having those Frito Bandito pencil erasers when I was in first or second grade.
When they realized that the Frito Bandito was offensive, they changed the mascot to “W.C. Fritos”
Similarly, another 1960s product was Pillsbury Funny Face Drink Mix (Goofy Grape, etc.). Two of their flavors were Chinese Cherry and Injun Orange.
They changed these to Choo Choo Cherry and Jolly Olly Orange.
When testing an HRIS for a former employee, I used Mildred Rached and Sigmund Freud as names for employees during our training. I worked with nurses and doctors.
My parents would have been very sorry if I had gotten my hands on a Woody Woodpecker kazoo; in fact, my wife would be even more sorry if I had one now.
I had a Woody Woodpecker door knocker, much to the consternation of my parents.
