On the invite-only passcode screen of the Pool app, a miniature yellow rubber duck mascot floats dynamically over a water-textured background. As the user tilts their device, the duck reacts to gravity via the gyroscope, sliding, drifting, and bouncing off the edges of the screen and the circular keypad buttons. This physics-based floating behavior creates a delightful, interactive easter egg that perfectly aligns with the pool brand concept.
