The Mimes level inside Shreck's Department Store is the first time Batman and Catwoman team up in LEGO Batman: Legacy of the Dark Knight, and it hides eleven collectibles across its retail floors: five Cat Heads, five WayneTech Caches, and one Red Brick. Grabbing all of them in a single run is possible if you know when to deviate from the main path, since several pickups are tied to specific abilities and short detours rather than puzzle-gated rooms.

WayneTech Cache 1: Portrait in the opening room
As soon as control returns after the rooftop cutscene with Batman and Catwoman, turn right instead of pushing forward. A large framed portrait hangs on the wall with yellow screws around its edges.
Step 1: Switch to Catwoman and target the yellow screws with her whip. Keep whipping until the painting drops away.
Step 2: Walk into the recess to collect the WayneTech Cache. The counter will tick up to 1/5.
Cat Head 1: Office corner
Continue into the second room, an office space. Look toward the back-right corner where a small cat-shaped ornament sits on a shelf. Smash it with any melee attack to register Cat Head 1/5.
WayneTech Cache 2: Key from the camera room
The objective updates to Find the elevator. Push into the room with two mimes and a bank of security monitors.
Step 1: Clear the mimes, then immediately turn left and destroy the desk near the cameras. A green key drops onto the floor.
Step 2: Carry the key back out into the corridor and use it on the locked door directly behind you. Inside, open the safe to take WayneTech Cache 2/5.
Cat Head 2: Statue in the elevator room
The next large chamber holds a wave of enemies and a central statue. After dealing with the mimes, look at the statue's outstretched hand. A Cat Head sits in its palm and goes down with a single Batarang throw.
Cat Head 3: Vent after the elevator
Following the elevator drop and the scripted floor collapse, take the staircase on the right up to the next landing. At the top, turn 180 degrees. A Cat Head sits inside the small vent tunnel behind you, easily picked off with a Batarang.
WayneTech Cache 3: The ambush room vent
After the staircase, a wider room triggers an ambush. Once every mime is down, the route forward opens, but the cache is tucked away on the right.
Step 1: Head to the right wall and smash the large crate against it. This exposes a vent grate that Batman can grapple open.
Step 2: Switch to Catwoman and use Call Kitty to send her cat through the smaller duct. The cat presses a button that lifts a shutter on the far side.
Step 3: Enter the now-open room and push the loaded cart against the back wall. Climb up and grab WayneTech Cache 3/5 from the terminal.
WayneTech Cache 4: Inside the Pets store
Further on, the path stops at a row of storefronts. The objective changes to Find a way past the doors. The Pets store sits on the left side of this plaza.
Step 1: Use Catwoman's whip on the spool above the Pets shutter to raise the door. Move quickly because it will close again.
Step 2: Send Batman inside and aim his Batclaw at the plug on the shelving unit. Pulling it down reveals WayneTech Cache 4/5.
Red Brick 1: Gadgets store arcade puzzle
The Gadgets store sits directly across from Pets. A dance-pad style controller is on the floor with a loose plug nearby.
Step 1: Connect the plug into the TV at the back of the store to power on the screen. An arcade-style mini-game starts up.
Step 2: Step on the directional arrows to steer the green cat across the screen toward the red square in the bottom-right corner. Avoid the orange dog patrolling vertically.
Step 3: Reaching the red square spawns the Red Brick and unlocks the Feline modifier, which recolors outfits to white. The HUD will display "FELINE MODIFIER UNLOCKED" to confirm.
Cat Head 4: Above the Sports Goods storefront
Push deeper into the store until you trigger a second large arena fight, this one including giant enemies. After the encounter ends, look toward the back-right where the Sports Goods sign sits. A Cat Head perches just above the storefront and can be knocked down with a Batarang.
WayneTech Cache 5: Music store piano puzzle
The Music store sits on the left side of the same plaza. A red pressure plate inside triggers a short sequence on the giant piano keys laid out across the floor.
Step 1: Stand on the red button to watch the demonstration. Memorize which keys light up and in what order.
Step 2: Step on the piano keys in the same sequence. Correctly replaying it pulls the curtain back to reveal a terminal holding WayneTech Cache 5/5.
Cat Head 5: Above the Shrecks sign
The final stretch tasks you with building a contraption in the middle of a wide room. Before you assemble anything, turn around and look up. The fifth Cat Head sits mounted above the large Shrecks logo behind you. Knock it loose with a Batarang to complete the set at 5/5.
Rewards for a full Mimes clear
Collecting all five Cat Heads adds the Cat Head trophy to the Batcave display. The Red Brick grants the Feline modifier, a cosmetic option that turns character outfits white. The five WayneTech Caches feed into the broader gadget and upgrade progression tied to Wayne Enterprises tech across the campaign.
If anything slipped past on the first run, the mission is fully replayable from the Batcave's mission terminal, and any previously collected pickups will not reappear or block the rest of the level.
