The Pet Netch is a floating, jellyfish-like creature with a bulbous, translucent body that glows softly in various shades of blue and purple. Its underside features delicate, trailing tendrils that move gracefully as it hovers. The surface of its body is smooth with a slightly iridescent sheen, and it has small, bioluminescent spots scattered across its form, giving it an ethereal appearance. The Netch's proportions are balanced, with a rounded main body and slender tendrils, making it both elegant and whimsical.
