At the top of the Cartoon Style image, the text "Happy Birthday Nadia" twinkling as colorful alphabet string lights in bright neon candy colors.

A cute, playful Stranger Things scene in a bold, thick-outlined Cartoon Style:

- Center focus: A chibi Demogorgon with exaggerated proportions (big petal head like a friendly flower, tiny arms and legs), wearing a polka-dot party hat, joyfully hugging a sprinkle-covered cupcake. Its petal interior is stylized with pink frosting tones and star sprinkles (no scary teeth), giving it an adorable, non-threatening look. One little hand holds a shiny star balloon.

- Setting: A Hawkins-inspired forest clearing at pastel dusk, with pine trees and cozy suburban silhouettes (water tower and small-town rooftops) in the distance. Strings of festive fairy lights drape between trees, casting a soft glow. Retro 80s bikes lean against a fence for that Hawkins vibe.

- Whimsical “Upside Down” touch: The ground subtly mirrors the scene below in a dreamy, pastel-blue reflection with friendly, swirly vines and floating sparkles—cute, not creepy.

- Birthday energy: Bright saturated palette (electric blues, neon pinks, mint greens, lemon yellows), confetti and streamers swirling, dynamic cartoon motion lines, and soft bubbly highlights. Thick inked outlines, soft shading, and glossy sticker-like surfaces for a fun, playful finish.

- Composition: Vertical portrait with generous image area; the glowing headline at the top; main character large in the middle; space at the bottom for a tiny caption.

At the bottom of the image, add a small, cheeky caption in a hand-lettered neon glow: "Have an Upside-Down-derful day!"
