Many sets include plastic ducks (examples show counts like 20 or 8), plus a pond or motorized pond base, instructions, and sometimes a sticker sheet or small figures.
They’re commonly listed for 2–4 players with a playing time of around 10 minutes.
Players float the ducks in water, flip them over to read numbers on the bottoms, and collect matching pairs by finding the corresponding numbers.
Motorized versions include a pond-shaped motor unit that spins or moves the ducks. Typical contents listed include eight rubber ducks, a sticker sheet, and instructions.
Motorized pond games list a requirement of 2 AA batteries (required but not included).
