At the top of the card, "Alan":

At the bottom, add "Even Batman Needs a Pit Stop to Celebrate!"

- In the center of the card, illustrate a comical scene where a miniature Lego Batmobile is parked at the edge of a whimsical birthday party.

- Perched on the roof of the Batmobile is a Lego Batman figure, wearing a tiny birthday hat that looks slightly askew, adding a humorous touch.

- Surround the Batmobile with an array of colorful Lego balloons tied to its antenna, each with an expression of glee as if they're ready to float away.

- In front of the Batmobile, show a line of Lego characters queuing up at a small Lego cake stand. The cake is brick-built, with layers of vibrant colors and a single oversized candle on top.

- The background depicts a bustling party scene set in a miniaturized Lego city. Skyscrapers are adorned with tiny banners and streamers, and Lego party guests are mingling, some with surprised looks, others holding miniature gifts.

- A Lego Joker figure is cheekily trying to sneak into the party unnoticed, carrying a gift wrapped in signature purple and green.

- Include a sky made of Lego clouds with a blocky sun peeking through, casting a warm, festive light over the entire scene.
