The mascot meeting. Very jarring as Coco and Nuts walking through the hall in their human form purposefully, only to open the door in mascot form and greeted by a sight that is best described as kindergarten class.
When she rescues Tsubomi from getting beaned by a Miracle Light, she skids across the road and promptly faceplants on the ground. Recovering, she's quick to scold Chiffon for her actions (telekinetically playing with the Lights), which causes her to cry and rain all of the floating Lights on every one while Miki, Buki and Setsuna coo and comfort the baby fairy, leaving Love to utter "But... she was bad..." before being beaned by a Light.
When the Fresh girls take Tsubomi and Erika to be treated for their troubles, Miki, Buki and Setsuna explain that they were supposed to meet up with everyone perfectly, but Love ended up misplacing the tickets. Love's reactions to their prodding is priceless.
Miki: It's not Love's fault she lost the tickets!
Setsuna: That's right. We were the ones who put Love in charge of the tickets.
Miki: And we were supposed to meet up perfectly. [Love, the entire time, goes from "Yeah, yeah..." to "..."]
When they meet up with everyone, it turns out everyone messed up - Nagisa also lost her tickets and Saki and Nozomi couldn't read maps to save their lives!
In DX 3, the yellow and purple team enjoying themselves too much in their mini games unlike the other teams; from Urara throwing the dice enthusiastically, the bowling mini-game ends with Yuri tripping the last ultra mini Uzaina to death, to Yuri winning studying contest (complete with 'Scary Shiny Glasses'), all while Rin playing Only Sane Woman before carried away by the nuance.
In blue and white team, Erika is the only one who falls into the sea ungracefully. You can see that Mai actually facepalmed in background at this.
Pink team shows just what happens if you have a team filled mostly out of Idiot Heroines.
New Stage; Suite team intro has Hibiki searching Fusion pieces with a magnifying glass like in detective cartoon and dramatically pointing to one direction. The screen then pans to Hummy and the Fairy Tones noisily eating corn cobs. Ellen lampshades Hibiki's antics, all while a seagull perches on Hibiki's head making Aside Glance for the entire scene.
A blink-and-you-miss it; when Sunny names their teams' Combination Attack Doki-Doki Smile Miracle Bomber, Rosetta becomes a tsukkomi to her boke. As Akane is usually the tsukkomi of her team, suddenly out-tsukkomi'd by someone else (and her reaction to it) is really hilarious. Not to mention, Rosetta is in her usual pleasant smile when she says it.
