I had some books given to me, from when both my Mom and I were children, after my Mom passed away. The box included the book, “Little Black Sambo” which has the tigers fighting each other by grabbing each others tails while running around a palm tree and going so fast that they turn into butter. The father gets a jar and takes the butter home to his wife to use in the making of pancakes! Is that what you’re referring to?
I have to edit out the racial references when reading the book but otherwise the story is cute and it’s a brightly colored book so it fascinates my 3 year old granddaughter.
