At the top of the image, "Erin, you’ve officially hit Level 18 — now you’re LEGENDairy Time!"

- In the center of the image, depict an Adventure Time-style scene where Erin is riding a giant flying birthday cake like it’s a dragon through a surreal candy-colored sky. She's dressed like Finn, but with 18 candles blazing on her head like a flaming crown.

- Behind her, Jake (the stretchy dog) is stretching into the shape of a giant “1” and “8” with confetti cannons strapped to him, launching streamers and glitter everywhere.

- Nearby, Lumpy Space Princess is holding a big sparkly balloon that reads “You’re not a teen anymore, lumpin’ DEAL WITH IT.”

- All around the scene, sprinkle little joke signs like “Adulting This Way ⟶ (Spoiler: It’s a Trap!)” and “Free Cake Taxes Ahead!”

- At the bottom of the image, add the caption: “No license required for this birthday adventure—just vibes, snacks, and eternal silliness!”
