Designed with a big stylized numeral “one” in lime green, dotted with small pink, blue, and yellow circles and edged with a scalloped white outline for a candy-like look. A single candle sits on top, its golden flame glowing softly like a tiny birthday spotlight 🎂. Peeking from behind the number on the left is a small blue animal in a pink cone party hat, leaning forward with wide, curious eyes as if sharing the moment with a friend. Near its paws rests a yellow gift with orange dots and a bright pink ribbon, adding a sweet surprise 🎁. On the right, a long-necked spotted creature in matching party headwear tilts its head with a gentle, amused smile, as though exchanging a warm glance across the scene. Below, a small rosy cat-like character sits close by, looking up with calm, affectionate eyes and a little tuft of fur on its head. The greeting “ONE” appears as the central numeral, while the rest of the background stays plain white so the pastel characters, candle, and gift stand out clearly.
