Blue dropping his rose during his henshin, and scrambling to pick it up.
During a mid-leap freeze-frame scene, Blue breaks the fourth wall by continuously glancing to his side, then swings his sword around a bit. He then drops his sword, and goes to retrieve it, then swims up the screen. He's out of position when the freeze ends, and ends up getting knocked around by a bunch of other Wonderful Ones.
When Wonder Green is a bit upset that Wonder Red - a rookie with barely a month on the team - is the leader after Green's introduction, he demands to know Red's tactical exams scores. Red reveals that he scored 100 on the written while 98 on the field. The Jaw Drop and unspoken Big "WHAT?!" looks on both Green and Blue respectively is priceless.
The moments where Wonder-Green tries to hit on Wonder-Pink, and then Pink's responses to them.
SO MANY QTEs have hilarious failure results. Failing to create the arrow for the Goddess of Blossoms' bow has the statue turning to SHRUG AT THE CAMERA before slide whistle falling off-screen. In an earlier QTE, not forming Unite Gun has Wonder Green hit by a building and knocked into sky, complete with a sparkle and A FADE-IN PICTURE OF HIM GIVING A THUMBS-UP. You will laugh at one or more of these. You can watch all of the QTE failures on this channel.
Upon being sliced in half, Laambo literally calls shenanigans on the Wonderful One-Double-Oh for defeating him.
Later, his brother Walltha says the same thing.
The second boss clings onto the Virgin Victory just after you kick its ass in an attempt to perform a self destruct sequence to take down the ship. How do you get the jerk off? You use Unite Hand to tickle it.
Perhaps even funnier is the QTE fail; all of the ships fly out of the way as Platinum Robo quickly swims to the Earth and moves it out of the way of the shot. The QTE then restarts to let you try again.
And if you pay attention, while everyone is frantically button mashing as much as they can, Wonder Yellow is slowly pushing his own button, only managing 3 presses while on screen.
Another from the final battle! Red, much to Blue's annoyance, decides to name their final attack something completely ridiculous. Blue ends up yelling in frustration right before getting punched out by Red. Later, Green notes that Red used the adjective "Final" twice.
Green, upon hearing that CENTINALS has someone giving information to GEATHJERK: When intelligence leaks, it is usually me!
The look on Pink's face is priceless.
There's also the reverse of that, which is THE ENTIRE WONDER-TEAM giving her the exact same look for fawning hopelessly over Prince Vorkken. The later version includes Luka and Immorta also giving her that expression, and it's hilarious.
If you die as Pink during any of the Vorkken boss battles, rather than her usual death shriek, she yells "VORKIIIIIIEEEEE!!!" instead.
This little lyric from the theme song, because of how (intentionally) ridiculous it is: "Go, go team! Demolish those fiends! Toss 'em in a garbage can!"
