I read a children’s picture book in the mid to late 80s in the US that was about moral lessons/behaving. Sorry, can’t remember what the cover looked like. There’s probably like 10 stories including: 1. A young hippo waits too long on a train to use the bathroom and poops his pants. An older animal tells him if he pays attention to his tummy and uses the toilet, the other animals will want to spend time with him. 2. A mother tells her young child (sorry, forget what type of animal it is) that electricity is dangerous and warns against putting things in the electrical outlets. A monkey encourages the child to stick a knife or fork in the socket and the child says no, so the monkey does it himself — book shows monkey getting electrocuted. 3. A panda or bear goes walking and ends up getting lost even though his mom warned him against it. The police end up getting involved. 4. There’s also a story about behaving for the babysitter when your parents go out and/or a story about how to behave when you get a new sibling. There’s no humans in the book and the illustrations are cartoony, not super realistic.
