Dolphin Party Splash 紙コップ

Make every sip a celebration with a smiling dolphin leaping from the waves, framed by balloon bunches at the top corners. The arched “Happy Birthday” with the celebrant’s name above the dolphin adds festive cheer, while the bold “Dive Into Fun” tagline at the bottom completes the design. Bright aquatic tones, playful accents, and crisp dropshadow text create a lively party atmosphere. Perfect for kids’ birthdays, ocean‑themed gatherings, or anyone who loves marine life fun.
