SpongeBob and Squidward's Houses

Did you know you can find SpongeBob Squarepants's pineapple house and Squidward's Easter Island head house in LEGO Batman: Legacy of the Dark Knight?

If you look out of the windows from the Iceberg Lounge, you can actually see these two iconic cartoon homes side-by-side. I didn't know Bikini Bottom was actually in Gotham City!

Resident Evil 4 Reference in the Bat-Mite

When you enter the Bat-Mite Store, Bat-Mite tries to mimic the Merchant from Resident Evil 4, quoting his famous line, "What're ya buyin'?" In some cases, he's even seen wearing the same face covering as the Merchant.

A video game scene in a dimly lit room featuring a character dressed as a detective observing a Batman figure on a pedestal. Text reads: "Bat-Mite: What're you buy-- hang on. Phew, that one's hard on the vocal chords! No idea how he does it." The environment feels mysterious and adventurous.

Of course, Bat-Mite doesn't pull it with the same finesse as the Merchant, as he cuts himself off and says the quote is "hard on the vocal cords" and wonders how he does it.

American Psycho Card Scene

In one part of the game, Bruce Wayne slides his business card across a desk, and an NPC immediately starts complimenting the block's craftsmanship and asking about the eggshell stationery.

This is a reenactment of a scene from American Psycho. Coincidentally, Christian Bale, who plays Batman in the Dark Knight trilogy, also plays Patrick Bateman in American Psycho.

Five Nights at Freddy's: Want to Eat Batman

While exploring Gotham, Batman stumbles upon an animatronic bear that wants to eat him.

This is a reference to the iconic video game franchise Five Nights at Freddy's, in which animatronics like Freddy Fazbear eat people.

It's Always Sunny in Philadelphia Quoted

During a fight with the Penguin, he quotes a line from the black comedy sitcom It's Always Sunny in Philadelphia to you. He says, "So anyway, I started blasting."

This is a line and meme spoken by the character Frank Reynolds, played by Danny DeVito, who also played the Penguin in Batman Returns (1992).

Batman Smashes Car Street Fighter Style

During a part when Batman breaks Black Mash's car, he does so in a way that mirrors the Bonus Stage in Street Fighter 2.

For those unaware, the Bonus Stage has players smashing a vehicle to earn bonus points. The way Batman does it is a clear homage to the Capcom classic, and it's one of the harder easter eggs to miss.

I Think You Should Leave Reference

During a diner scene, the game references a scene from the Netflix comedy I Think You Should Leave. While the Netflix sketch shows a man attempting to buy a large amount of food to exploit the "Pay it Forward" chain, the LEGO Batman game addresses the reference a little differently.

In the game, a patron is heard asking the waiter for any dinner challenges. In response, the waiter says that if they can eat 55 burgers, 55 shakes, and 55 tacos, they'll be asked to leave. These numbers were lifted from the Netflix comedy.

Alfred Quotes Michael Caine

In August 2024, Michael Cain tweeted, "Why do we fall? So we can learn to pick ourselves up. Batman Begin." The tweet went viral because Cain forgot the 's' in Batman Begins.

In the game, Alfred delivers this exact line - typo and all. This is a chronically online reference, so it's bound to slip past some people. But hey, if you know, you know.
