Krei enlists Big Hero 6 to launch his new karaoke machine.
Tropes:
- Actually Quite Catchy:
- Honey Lemon is the only one who enjoys Krei’s “Krei-oke” song, as she’s seen bobbing along.
- Noodle Burger Boy keeps getting distracted by the Krei-oke performances, to the point where he can’t resist joining in on Granville’s song and ruins his own evil plan.
- Answer Cut: After Krei only manages to sell one karaoke machine, Hiro asks "I wonder who the sucker was?" Cut to Noodle Burger Boy singing a blues song on karaoke.
- Back for the Finale: This is the first half of the series finale and a lot of supporting cast members returned to sing a song.
- Beam-O-War: At the climax, after Noodle Burger Boy steals Krei's sonic cannon, hero tries to stop him with a spare sonic cannon hooked up to the Krei-oke system with Granville’s singing powering the beam.
- Cacophony Cover Up: The Krei-oke participants’ singing covers up Noodle Burger Boy and his team making a huge hole in the wall to break the sonic cannon out of Krei’s holding facility.
- Gosh Dang It to Heck!: After Wasabi's song and Krei finds that there are still no sales for the Krei-oke machines yet.
Krei: Aaaannd....BUPKIS!! Oh, there goes the farm!
- Grand Finale: The first half of the series finale.
- Hidden Depths: We get to hear talented singing from a large number of characters.
- "I Want" Song: Noodle Burger Boy’s song about how much he wants a sonic cannon.
- Jaw Drop:
- Wasabi when Honey Lemon sings a hard rock song.
- A collective one by Hiro, GoGo, Honey Lemon and even Baymax (through an emoji on his screen) when they witness Granville singing during the karaoke. They are clearly shocked that she has such talent.
- Karaoke Box: The plot revolves around Krei launching a karaoke machine.
- Literal Metaphor:
- When Krei says he “bet the farm” on the Krei-oke machine, he means it literally as he actually did bet the family farm on the machine's success.
- Also, due to the Mascots busting Krei’s sonic cannon out of the building, when Granville is singing the roof is literally blown off.
Krei: Wow! She blew the roof off!
- Musical Episode: Almost all of the characters take a turn singing with the Krei-oke machine.
- Musicalis Interruptus: Noodle Burger Boy is singing “The Noodle Burger Blues” until Crushroom throws him out the window and then sends his Krei-oke machine crashing down after him.
- Nice Job Fixing It, Villain: Noodle Burger Boy’s high note provided the surge of power that allowed Big Hero 6’s own sonic cannon to defeat the one the Mascots were stealing from Krei.
- Pun-Based Title: A play on the character Krei and “karaoke” - also the name of his karaoke machine.
- Sidetracked by the Analogy: Crushroom gets confused when Noodle Burger Boy starts speaking in food metaphors, to the point where Hangry Panda has to explain them to her.
Noodle Burger Boy: I was cooked up in the Krei kitchen.
Crushroom: Crushroom confused by food metaphor.
Hangry Panda: He can still tap into the Krei network because he was built there.
- Sonic Stunner: Krei's latest invention, besides the Krei-oke, is a sonic cannon powerful enough to level buildings. He meant it for demolition, but as the heroes point out, it could be used as a weapon, which is why Noodle Burger Boy is after it.
- Traveling-Pipe Bulge: A bubble of energy is seen traveling through the cord towards the sonic cannon being manned by Baymax due to Noodle Burger Boy’s powerful high note.
