Making a change
Another classical reference in The Little Mermaid. The sea witch Ursula uses her magic to turn into a human with Ariel’s voice and woo the Prince. Her human name is Vanessa, which doesn’t seem that important.
However, one of the ingredients for the spell she uses is a butterfly. Not only is the butterfly a symbol of transformation for different cultures (due to its creation via metamorphosis), but Vanessa is one of the most common types of butterflies.
