Why Flounder’s Little Mermaid Outfit is Necessary
As a long-time fan of Disney’s The Little Mermaid, I can’t help but appreciate the charm and personality that Flounder brings to the story. His iconic outfit—bright yellow and blue stripes—does more than just make him visually appealing; it serves several important purposes that enhance both his character and the overall narrative.
Firstly, Flounder’s outfit reflects his vibrant personality. Whenever I see those bold colors, I am instantly reminded of his playful nature and loyal friendship with Ariel. The bright hues help to distinguish him in the underwater world, making him stand out against the often darker shades of the ocean. This visual contrast not only adds to the animation’s aesthetic but also makes it easier for viewers, like myself, to connect with him emotionally.
Moreover, Flounder’s outfit plays a significant role in conveying his character traits. The stripes can symbolize his youthful exuberance and innocence, while the colors suggest a sense of adventure. As a sidekick, Flounder often finds himself in situations that require bravery, and his outfit serves as a reminder of his journey from a timid fish to a courageous companion. When I see him donning those stripes, I feel inspired by his growth
