Duolingo Combo 5 Thunder Mascot Animation

Upon completing a correct chess puzzle move, a multi-layered reward animation triggers. The progress bar at the top fills with a vibrant orange gradient, displaying a 'COMBO x5' badge while lightning sparks crackle. Simultaneously, the mascot character instantly transforms into an energized 'thunder' state with pink hair, glowing eyes, and electrical sparks. A success bottom sheet slides up from the bottom of the screen with a bouncy spring, presenting a green 'CONTINUE' button and a checkmark icon to celebrate the user's progress.
