Aesop's Fables (1983)

A mischievous boy named Aesop loves wreaking havoc around his village. One day, when all his trouble making eventually leads him into a perilous situation, he winds up getting lost in a fantastical world that is unlike his own. He meets and befriends the inhabitants there, including a spring elf named Pitchi (Silkwing in the English dub), a mouse named Chuchu (Skitter in the English dub), and a donkey named Barrow (Hawhee in the English dub). He comes across others who would become the characters in his stories, including those from The Boy Who Cried Wolf, The Country Mouse and The City Mouse, The Tortoise and The Hare, and The Grasshopper and The Ants. After the adventure and experience he's had, he learns a valuable lesson.
