At the top of the image, "Erin, you're finally 18—time to go on a totally algebra-licious quest for adulting!"

- Illustrate a whimsical cartoon scene in the iconic Adventure Time style, with Erin reimagined as a heroic adventurer (think Finn with sass), wearing a glittery birthday crown, oversized boots, and wielding a giant ID card like a sword.

- She’s riding a candy-colored creature that’s a mash-up of Jake the Dog and a giant inflatable unicorn, galloping across a landscape made of cake hills and soda pop rivers.

- Balloons shaped like legal documents float overhead with silly faces, and in the background, a "Level 18 Unlocked!" treasure chest spills out car keys, student loans, and glitter.

- Bonus: Add a sidekick that looks suspiciously like a sentient debit card wearing shades and yelling, "Swipe responsibly!"

Generated with these themes: Adventure time, 18 year old, and Happy birthday.
