Cartoon Cetacean Party Card

This design shows an underwater birthday scene where two friendly cartoon sea mammals face each other with a tender, close-in gaze, like best friends sharing a private joke 🎉. One is a deeper blue and the other leans teal, and both wear polka-dotted cone party hats topped with small pom-poms. Between them sits a three-tier cake with white frosting, drips of purple icing, and tiny red sprinkles, finished with a single lit candle. The darker blue character on the left holds a shiny fork near the cake, while the lighter one smiles wide with rosy cheeks, leaning in as if cheering the first bite 🎂. Soft blue-green water surrounds them, with gentle light fading towards the edges to keep the centre bright. The words “Happy Birthday” appear above the cake in rounded blue letters, centred near the top. Bubbles rise around the pair, with green seaweed swaying behind them over a warm sandy seabed.
