Cartoon Siren in a Moonlit Graveyard

Cartoon-style illustration of a friendly siren with turquoise hair and a shimmering teal fishtail, wearing a seashell top and a coral crown, perched on a cracked tombstone in a foggy graveyard. Bold outlines and flat, bright colors in a classic 2D animation look. Moonlit night with a pale moon in wispy clouds, glowing fireflies, and rows of old tombstones with a weathered statue in the background. The siren smiles and blows bubbles that float and transform into tiny sea-creature shapes; subtle water reflections ripple on the ground around the graves, hinting at her ocean origins. Whimsical yet slightly spooky atmosphere.
