Rubber Duck details
Where all Rubber Duck locations appear
The full Rubber Duck set is found during The Penguin mission. The ducks are spread across the natural progression of the level, so the best method is to move carefully from one objective area to the next and scan the route before pushing forward. All the Rubber Ducks are found in the Arctic World.
Rubber Duck 1
The first rubber duck is available during Catwoman’s Wall Climb.
After clearing the wall climb, pull the lever.

The location route inside The Penguin mission
All five Rubber Duck locations are tied to The Penguin mission itself. That makes this collectible set more about careful route awareness, and it also means a steady full run is usually enough to collect everything in sequence. If you follow the mission in order and stay alert at each transition area, collecting all five Rubber Ducks is very manageable in a single run. The key is to clear each section carefully, grab each duck as it appears, and do not sprint past the collectible path.
