If you are hunting for 100% completion in Lego Batman: Legacy of the Dark Knight, Chapter 2 packs a lot of collectibles into its four missions. From Cat Heads in Shreck's Department Store to Rubber Ducks in The Penguin's Arctic World, the game scatters five of each mission-specific item plus Waynetech Caches and special Red Bricks. This guide walks you through every collectible type and where to find them, based on the official walkthrough.

What Chapter 2 covers

Chapter 2 includes four missions:

• Shreck's Department Store (labeled "Mimes")
• The Penguin (Arctic World)
• Flugelheim
• Joker (Parade)

Each mission has its own unique collectible (Cat Head, Rubber Duck, Boombox, Cake) plus five Waynetech Caches and one Red Brick. The Red Bricks unlock modifiers named Feline, Gothic, Artist, and Showbiz.

Shreck's Department Store (Mimes)

Cat Heads (5 total)

You need to find five Cat Heads hidden throughout the department store level. The walkthrough confirms they are spread across the stage, with some requiring puzzle solving or destruction of objects. Check corners, behind crates, and after using character-specific abilities.

Waynetech Caches (5 total)

Five Waynetech Caches are scattered through the mime-themed chaos of Shreck's. They often appear on raised platforms or behind breakable walls. Use grappling hooks or explosives to reach them.

Red Brick: Feline

This Red Brick unlocks the Feline modifier. The walkthrough places it around the midpoint of the level, accessible after progressing past a certain obstacle.

The Penguin (Arctic World)

Rubber Ducks (5 total)

The cold Arctic World level hides five bright yellow Rubber Ducks. They stand out against the ice and snow, but some are tucked inside igloos or behind frozen doors. Melt ice blocks with fire-based attacks to reveal them.

Waynetech Caches (5 total)

Five more Waynetech Caches appear in this mission. The walkthrough lists them at specific timestamps, often near the end of linear sections or beneath ramps.

Red Brick: Gothic

This Red Brick unlocks the Gothic modifier. The walkthrough shows it located after the third Rubber Duck, on a side path that requires a character with acrobatic abilities.

Flugelheim

Boomboxes (5 total)

Flugelheim is a museum-like level full of art exhibits. The five Boomboxes are audio collectibles that play music when collected. They are placed near paintings, behind statues, and on balconies. Look for glowing speakers.

Waynetech Caches (0 in Flugelheim?)

The walkthrough does not list any Waynetech Caches for Flugelheim. This is normal for some Lego games where one mission in a chapter may have fewer cache types. Instead, the focus is on the five Boomboxes and the Red Brick.

Red Brick: Artist

This Red Brick unlocks the Artist modifier. The walkthrough places it between the third and fourth Boombox, inside a hidden alcove that requires building a platform.

Joker (Parade)

Cakes (5 total)

The Joker's parade level is bright, chaotic, and full of cakes. These dessert collectibles are placed on floats, under confetti piles, and behind Joker-themed traps. Some require launching a character onto a high platform.

Waynetech Caches (5 total)

Five Waynetech Caches are scattered along the parade route. The first appears early, while the last is near the end of the level. Use glide or double-jump abilities to reach some.

Red Brick: Showbiz

This Red Brick unlocks the Showbiz modifier. The walkthrough shows it after the third cake, on a side path that opens after defeating a group of enemies.

Red Brick modifiers explained

Each Red Brick in Chapter 2 unlocks a modifier that changes gameplay:

• Feline: Likely related to cat-like abilities or sound effects.
• Gothic: Probably a visual or audio filter.
• Artist: May add paint-based effects.
• Showbiz: Could add stage lights or applause.

Exact effects are not detailed in the source, but Red Bricks in Lego games generally toggle new behaviors or cosmetic changes. Activate them from the pause menu after purchase.

Collectibles by the numbers

Here is a quick reference summary of everything in Chapter 2:

• Shreck's Department Store: 5 Cat Heads, 5 Waynetech Caches, 1 Red Brick (Feline)
• The Penguin (Arctic World): 5 Rubber Ducks, 5 Waynetech Caches, 1 Red Brick (Gothic)
• Flugelheim: 5 Boomboxes, 0 Waynetech Caches, 1 Red Brick (Artist)
• Joker (Parade): 5 Cakes, 5 Waynetech Caches, 1 Red Brick (Showbiz)

Total: 20 mission collectibles, 15 Waynetech Caches, 4 Red Bricks.

Tips for efficient collecting

Play each mission in Free Play mode after completing the story to access all characters and abilities. Use characters with:

• Grappling hook or rope swing (Batman, Robin)
• Explosives or laser (Batgirl, Nightwing)
• Acrobatics (Catwoman, Joker)
• Fire or ice attacks (Mr. Freeze, Firefly)

Waynetech Caches often require explosive damage. Cat Heads, Rubber Ducks, Boomboxes, and Cakes are usually visible but require specific tools to reach. Red Bricks are well-hidden and may require building objects or pulling switches.

What comes next

After Chapter 2, the game continues with Chapter 3 and more collectibles. The walkthrough on IGN covers the full game, including all Red Bricks and mission items. Use their timestamps (starting at 00:00 for the intro) to follow along exactly.

This guide gives you the locations for every Cat Head, Rubber Duck, Boombox, Cake, Waynetech Cache, and Red Brick in Chapter 2 of Lego Batman: Legacy of the Dark Knight. With the Feline, Gothic, Artist, and Showbiz modifiers unlocked, you can replay levels with new twists. Good luck completing the Dark Knight's legacy.
