The swan princess (1994)

The beautiful princess Odette is transformed into a swan by an evil sorcerer's spell. Held captive at an enchanted lake, she befriends Jean-Bob the frog, Speed the turtle and Puffin the bird. Despite their struggle to keep the princess safe, these good-natured creatures can do nothing about the sorcerer's spell, which can only be broken by a vow of everlasting love.
