At the top of the Illustration Style image, "Happy 5th Birthday Ivan!" in big, bouncy hand-lettered brush script, warm crimson with a creamy off‑white outline, arcing like a trampoline spring.

Hand-drawn illustration with fine linework and textured brush strokes, warm expressive palette of sunset oranges, jade greens, and deep indigos. A playful “Ninjango” scene: a wooden-beam ninja dojo built around one giant round trampoline as the “dojo floor.” Five adorable kid ninjas (diverse, giggling) in colorful gi and headbands are mid-bounce, flipping and flying with exaggerated motion arcs and swoosh lines. One clumsy sensei with a huge mustache is accidentally airborne, sandal flipping comically, while confetti shaped like foam ninja stars floats around. Paper lanterns sway overhead, bamboo railings frame the scene, and a tiny drum on the side is wobbling from the boing. Balanced composition: the trampoline centered, characters arranged in a lively circle, warm golden light and soft paper-grain texture, subtle inky crosshatching, clean background space near the top for the headline, and a gentle vignette to keep the focus on the action. Funny, energetic, and kid-friendly.

At the bottom on a small hanging banner, add one cheeky line in playful brush lettering: “Master of the Flip-ty-Five!”
