  "textContent": "The first proper introduction to the Riddler in Lego Batman: Legacy of the Dark Knight comes through the Riddle Me This side quest, which unlocks after the Tricorner Investigation against Cobblepot. Harvey Bullock hands Batman and Jim Gordon an address pulled from a greeting card, and that address turns out to be the Tricorner Puzzle Room, a green-soaked chamber built around three back-to-back mirror puzzles.\n\n🟢\n\nQuick answer: Match each set of pedestals to the objects shown in the mirror's reflection. Room 1 needs the bear, room 2 needs the top hat, lamp, and candlestick (left to right), and room 3 needs the lamp from room 2 plus the boombox, with the piano lowered using the handle.\n\nImage credit: __Warner Bros.

Three pedestals sit in front of a large mirror, and only one of the reflections shows an object resting on a plinth: a green teddy bear.\n\n**Step 1:** Find the green teddy bear sitting on a plinth nearby and pick it up with the Pick Up prompt.\n\nPick up the green teddy bear | Image credit: __Warner Bros. Games, Warner Bros. Interactive Entertainment (via YouTube/@Perfect Score)__\n\n**Step 2:** Carry the bear to the empty pedestal that corresponds to the reflection and place it. The mirror slides open into the next chamber.\n\nConfirmation: the mirror physically opens, and the objective updates to _Complete the second mirror puzzle_.\n\nImage credit: __Warner Bros. Games, Warner Bros. Interactive Entertainment (via YouTube/@Perfect Score)__\n\n* * *\n\n### Mirror room 2: Top hat, lamp, candlestick\n\nThe second room has three empty plinths in front of a fresh mirror. The reflection shows three items in this order, left to right: a top hat, a lamp, and a candlestick. The objects themselves are scattered around the room, with one hidden inside a pile of Lego boxes in the corner.\n\n**Step 1:** Smash the green Lego boxes in the corner to reveal the green top hat. Ignore the pink candelabra you might pick up first; it's a decoy.\n\nSmash the green Lego boxes in the corner to reveal the green top hat | Image credit: __Warner Bros. Games, Warner Bros. Interactive Entertainment (via YouTube/@Perfect Score)__\n\n**Step 2:** Place the top hat on the leftmost pedestal, the green lamp on the middle pedestal, and the candlestick on the right pedestal so the arrangement matches the reflection.\n\n**Step 3:** Once all three line up with the mirror, the second mirror slides open, and the objective updates to _Complete the third mirror puzzle_.\n\nOnce all three line up with the mirror, the second mirror slides open | Image credit: __Warner Bros.

Some objects are hidden inside breakable Lego props, and you'll collect Studs at the same time.\n\n* * *\n\n### Mirror room 3: Lamp, boombox, and the piano\n\nThe third room is the trickiest of the three because the reflection shows a lamp and a boombox on the pedestals, plus a piano lowered into the background. The piano is suspended above the room and has to be brought down using a crane handle on the side.\n\n**Step 1:** Break the shelves to the left of the room to reveal the boombox (a green box). Place it on the correct pedestal in front of the mirror.\n\nBreak the shelves to the left of the room to reveal the boombox | Image credit: __Warner Bros. Games, Warner Bros. Interactive Entertainment (via YouTube/@Perfect Score)__\n\n**Step 2:** Backtrack to room 2 if needed and bring the green lamp forward, then set it on the matching pedestal so both objects align with the reflection.\n\n**Step 3:** Interact with the crane mechanism to move the piano (the yellow/suspended object) into position so it matches the background of the reflection. The third mirror slides open.\n\nInteract with the crane mechanism to move the piano | Image credit: __Warner Bros. Games, Warner Bros.

The cage opens automatically once you approach.\n\nWalk up to the trophy and use the Collect prompt. The HUD will flash **Riddler Puzzle Box 1/9 Tricorner** followed by **Puzzle Room 1/1 Tricorner** , confirming the room is cleared. The objective then changes to _Leave the Riddler Room_.\n\nImage credit: __Warner Bros. Games, Warner Bros. Interactive Entertainment (via YouTube/@Perfect Score)__\n\n* * *\n\n### What unlocks after Tricorner\n\nSolving the first Puzzle Room marks the next one on Gotham's map. Puzzle Rooms use a Puzzle Box icon, while smaller individual Riddler puzzles use the standard Question Mark icon. The progression continues through The Cauldron North, Old Gotham North and West, Gotham Village's Robinson Park, Newtown, and East End Amusement Mile, with several later rooms gated behind specific characters.\n\nPuzzle Room| Character requirement\n---|---\nTricorner 1| Batman and Jim Gordon (story default)\nThe Cauldron North| Batman\nOld Gotham North| Batman (grapple + ranged)\nOld Gotham West| Catwoman (Whip) + Batman (UV Vision, Spray Explosive, grapple)\nGotham Village – Robinson Park| Catwoman + Batman\nNewtown| Talia (Ninja Dash)\nEast End Amusement Mile| Batgirl (Hack, Drone)\nImage credit: __Warner Bros. Games, Warner Bros. Interactive Entertainment (via YouTube/@Perfect Score)__\n\n* * *\n\n### Common reasons the mirror puzzle won't complete\n\nIf a mirror refuses to open after you've placed objects, only a few things are usually wrong. The object order in room 2 has to match the reflection from left to right, not in any order. In room 3, the piano needs to be physically lowered using the crane handle; placing both items on the pedestals without aligning the piano leaves the puzzle unfinished. And the bear in room 1 must go on the specific pedestal where the reflection shows it, not on any open plinth.\n\nPicking up the wrong decoy item (such as the pink candelabra in room 2) doesn't break the puzzle. Drop it and grab the correct object. Once every pedestal matches and the background elements line up, the mirror animation plays on its own.",
