Duolingo 150 Day Streak Animation

The interaction begins with a shaking egg that cracks open to reveal Duo the owl, who bursts upward and morphs into a flaming, sunglasses-wearing mascot. The streak number '150' springs into view, followed by a horizontal calendar tracker sliding up. A small flame drops onto the final day of the week, triggering a checkmark. Next, action buttons slide up from the bottom. Tapping 'Share Milestone' slides up a customized share card inside a bottom sheet with social sharing options. Tapping the close button dismisses the sheet, returning to the main streak screen.
