In the foreground of the card, place a chubby, lifelike hamster standing upright on a round stage. The hamster is gripping an electric guitar with its tiny paws, the guitar's body a glossy cherry red with a white pickguard and shining metallic strings. The hamster's fur is a mix of sandy brown and creamy white, with its round black eyes gleaming under the stage lights.

Behind the hamster, unfurl a large "Happy Birthday" banner that stretches across the upper part of the card. The banner is vivid blue, with bold yellow letters that catch the eye.

To the right of the hamster, there’s an open pizza box perched on the stage. The pizza inside is cheesy with generous toppings of pepperoni and green bell peppers, the cheese glistening as if still warm. One slice is slightly out of place, as if someone (perhaps our furry friend?) has already sampled it.

In the background, add a hint of a lively party scene with a subtle blur effect. Balloons in various shades of red, blue, and yellow float upwards, their strings trailing down toward the stage. A few colorful streamers are draped from the top of the card, enhancing the festive atmosphere.

To the left of the stage, illustrate a small birthday cake with a single candle. The cake is chocolate with a swirl of vanilla frosting on top. Inscribed in vibrant icing on the cake's surface is the name "Josh" in elegant cursive.

The background should be a soft gradient from a sunny yellow at the top, fading into a pastel blue toward the bottom, suggesting a cheerful indoor setting bathed in artificial light. The overall composition is dynamic, drawing attention to the quirky rockstar hamster and the name "Josh" that subtly personalizes the scene.
