You're a mother duck. Pick up the ducklings waiting in puddles, and they line up behind you, hopping exactly where you hopped. Lead the whole parade to the pond. Bigger parades score far more, but every duckling has to survive the gaps you chose.
About 5–8 minutes a run · Swipe, or tap the side of the duck you want to hop toward. Keyboard: arrow keys or WASD. P pauses, M mutes.
