Look for an old cartoon. What I remember best is a brown turtle shell, as well as cows, camels and little girls. Egg yolk color cartoon.

Adventures of the Little Princess: The hero of the story is a princess in distress named Katina. She has a group of friends who live in the forest. She must embark on an adventure, because she wants to get the fountain of life and defend the whole country. Along the way, she and her friends fought to the death with the masked men of the pirate ship, and finally got the fountain of life. I still remember that the final outcome was that the little princess turned into a lake and merged with this country, while her friends were sad, but they could feel that Katina would live with them forever. The theme song of this cartoon was sung by almost all the children in the class at that time, so I also wrote it. "What a beautiful forest, the lakes and mountains are really charming, and the friends in the forest are the most United and brave. There is a masked man on the pirate ship who wants to occupy the mysterious fountain of life. Princess in blue is brave, not afraid of danger or hardship. Flying through Yuan Ye, full of stars, sailing. Protect the forest, be quiet and peaceful, bathe in the morning light and rush to the light. "
