Aquatic Echidna

Prompt

Illustrate a minimalistic icon of an echidna, another unique monotreme. The design should feature a simplified, rounded body with smooth lines, emphasizing its spiky back with a few geometric quills. The snout should be short and pointed, reminiscent of a small beak, while the legs should be represented as smooth, webbed feet. Employ a monochromatic color palette with one or two accent colors for a modern look, ensuring the overall shape remains clean and well-balanced for optimal use as a UI icon or logo.
