This 1994 animated film version of the classic European fairy tale was released by Warner Brothers. As in the original fairy tale, Thumbelina gets taken in by a family of toads. The mother toad wants her to marry one of his sons. The toads are part of a circus act in this animated release. They are loud and vain. They also try to exploit Thumbelina as part of their act.
Thumbelina is a blonde voiced by Carol Channing. Charo furnishes the voice of Mother Toad. Mother Toad's character definitely has an ethnically-identifiable voice which carries into her singing. The toad son is also similarly identifiable as Latino. The Toad son, coincidentally or not, happens to be pot-bellied and has a wispy black moustache. He proves to be a jealous villain who brutally clubs Thumbelina's slender, red-headed fairy prince.
I was pretty uncomfortable watching this. I would rather have no ethnic minority characters in a film than to see only negative ethnic minority characters. It is rather ironic that this animated feature has a Spanish language release.
