In the episode, Homer wakes up in an alternate reality where everyone and everything is made of Lego bricks, and he must figure his way out before he gets stuck in the plastic world forever.
Homer awakens in a utopian Springfield where everything and everyone is made out of Lego (Maggie is a massive Duplo figure).
While visiting the Lego Comic Book Guy's store to pick up a toy set for Lisa's birthday, Homer has a vision upon touching the box where he sees his normal flesh self giving the gift to Lisa and helping her build it, which disturbs Lego Homer.
As Homer wishes he could live in the Lego Springfield he created with her, where "everything fits together and no one gets hurt", Comic Book Guy's giant Lego construct of Kendah Wildwill (a parody of Katniss Everdeen from The Hunger Games) falls on Homer, knocking him unconscious.
Homer returns to the Android's Dungeon and learns that opening the toy box will end his fantasy.
He proceeds to fortify his store and sets Lego pirates and ninjas on Homer to keep him from reaching the box.
Hearing Homer's cries for help, Lego Bart builds a giant robot from various play-sets and takes down the pirates and ninjas before crashing onto the store.
Homer regains consciousness at the Lego contest and reunites with Lisa, who had come after feeling bad about leaving him.
In an April 2014, interview with TV Guide, executive producer Matt Selman spoke about how long it took to produce the episode, saying: "We've literally been at this thing for two years — twice the time it takes to do one of our regular episodes — and that's way too long for comedy people to live with the same jokes.
"We're pretty picky about how our brand is represented, and The Simpsons, which is so famous for its satire, has its own distinct point of view", said Jill Wilfert, the Lego Group's vice president of licensing and entertainment.
"[2] The idea of the episode was conceived several years previous to airing, when the toy company approached Fox about producing a Lego set of the Simpsons' home, including minifigures of Homer, Marge, Bart, Lisa, Maggie and Ned Flanders, which went on sale in February 2014.
"[2] The episode's writer Brian Kelley spoke about how the episode's extensive CGI forced the staff to work in a whole new way, saying: "With this style of animation, everything needed to be locked in very early on, meaning we had to settle on our story and our jokes and commit to them with no room for screw-ups.
"[2] Kelley also explained that a big church sequence in the episode gave the staff a chance to include all of Springfield's citizens, saying: "We pushed as much as we could to get everyone into those pews.
When you get right down to it, Lego is just bricks, and Matt Groening's design for our characters is really just eyeballs and a few lines — easy enough for any kid to draw.
Jesse Schedeen of IGN gave it an 8.2/10 "Great" rating, saying, "The similarities to The Lego Movie are unfortunate, but there's still a lot of fun to be had in this latest Simpsons milestone episode.
And the headier themes and story elements, if redundant at this point, should still connect with anyone who grew up playing with LEGOs.
"[5] Tim Surette of TV.com said, "By the time Bart came out in his twisted mech suit and barfed out lightsabers, 'Brick Like Me' was just a grab bag of random pieces coming together in an effort to form something bigger—kind of like the handiwork of a kid who showed up late to a Lego party and didn't get his pick of the pieces so he built whatever he could from odds and ends.
"[6] James Poniewozik of Time gave the episode a positive review, saying "'Brick Like Me' demonstrates that The Simpsons still has it, at least sometimes.
Maybe that isn't the case so much anymore, but there is still the capacity for top-notch television floating somewhere in The Simpsons universe.
"[8] Tony Sokol of Den of Geek gave the episode four and a half stars out of five, saying "So, I came in wary but no, it's a good payoff.
