All Rubber Duck Locations
1/5 - The First Rubber Duck can be found at the start of the level, once the first gate is opened.
2/5 - The Second Rubber Duck can be found in the combat encounter with the miniature penguin bombers. You'll find it on the left of the room floating in a pool of water.
3/5 - The Third Rubber Duck can be found on top of this painting of The Penguin
4/5 - The Fourth Rubber Duck can be found in the middle of the lake puzzle. Simply hit it with any ranged attack to collect it.
5/5 - The Fifth Rubber Duck can be found in the grips of this submarine, hanging in the area where you're tasked to retrieve a missing handle to shut off the ice.
All Wayne Tech Caches
1/5 - The First Cache can be found in the mini penguin combat encounter. The cache is up on a ledge which can only be reached with a jump pad. Break the white container you see in the image below with a ranged attack, and you will be able to construct the pad needed to reach the cache.
2/5 - The Second Cache is found on the way to the lake puzzle in the level. There is a very distinct glass piece being covered up by a cart. Simply move the cart out of the way, and cut a hole in the glass as Catwoman to reach this cache.
3/5 - The Third Cache can be found directly next to the previous one, guarded by an explosive snowman. Simply destroy it, and you can walk inside the guarded room to claim the next cache.
4/5 - The Fourth Cache can be found at the step of the mission where your character mentions retrieving a missing handle. After getting the handle and melting away the ice on this wall, have Batman spray his explosive gel on the wall. This will blow it open, and reveal cache number 4.
5/5 - The Fifth Cache can be found just behind the fourth. First, get Batman to throw one of his Batarangs through the glass to shut off the fans. Then, send Catwoman's kitty through the vent and have it retrieve the key inside the passageway. Once done, give the key to Catwoman, and place it in the hole next to the fence. Once done, the fence will lower, and you can grab the final cache.
Red Brick Location
In order to grab this Red Brick, take a sharp right from the picture of The Penguin early in the level and break the debris covering up a vent. Follow this through with Catwoman and you'll end up in a secret room with a puzzle featuring Penguin's Umbrellas. Simply pick up the correct color, and place it on the center pedestal. Using Catwoman's whip attack, angle it to aim at the cage holding the brick, and jump on the pressure pad on the left to fire it. When done correctly, the brick will be set free!
