Another option could be animations based on folktales from different cultures. For example, the Chinese folktale of 'The Magic Paintbrush' which is about a kind boy who has a paintbrush that can make things come to life. These types of stories promote cultural understanding and are suitable for all ages.
We could focus on family - friendly animations like those of Disney or Pixar. For example, stories about family adventures in movies like 'Finding Nemo' where a father fish goes on an epic journey to find his son. There are also many other animations that revolve around friendship, like 'Toy Story' which shows the strong bond between toys.
There are a great number of children's books that can be turned into animations. Take 'The Gruffalo' for instance. It's a story about a little mouse who uses his wits to outwit the scary - looking Gruffalo in the forest. This kind of story is full of imagination and positive values, which is a far cry from inappropriate content.
