- In the center of the image, feature a realistic-looking cake shaped like Olaf from Frozen 2. Olaf's wide, joyful eyes and carrot nose are perfectly sculpted in fondant. He's playfully holding a sparkler in one hand.

- Behind Olaf, create a snowy backdrop that gives the impression of a frozen wonderland, complete with sparkling snowflakes gently falling.

- To the left of Olaf, have a realistic ice sculpture of Elsa mid-song, as if she's belting out a birthday tune.

- To the right, add a mini realistic version of Sven, the reindeer, with a party hat on his head, looking amused as he nudges a stack of gift-wrapped presents.

- At the bottom, write in bold, whimsical font: "Have an Olaf-tastic Birthday!"

- Ensure the background captures the vibrant colors and magic of a birthday celebration in Arendelle, complete with balloons and streamers hanging between snowy trees.
