Goggles being in DS' Dream World house for no real reason and licking her candy table while she is having a conversation with Artemis, and the little Call Back when Artemis suggests Murder the Hypotenuse:
Pink, Goggles, Jane's Gallade, and the Greedy Golett somehow finding their way into fourth-wall breaking spoiler text.
And when Missingno ends up finding his way into the spoiler text, Jane forces everyone out of the spoiler text. Without actually fighting.
"This hair dryer is loaded, and I'm not afraid to use it!" What makes it even better is that while the Team Galactic grunt obviously doesn't take this threat seriously, DS does shortly afterwards manage to find a way to use the hair dryer as a weapon.
A much younger Tagg taking on Groudon in Yu-Gi-Oh!.
A vast number of hilarious things also happened to the rest of the group, such as Gamer turning into Gla DOS, Meddler turning into Amy Rose, DS becoming invisible, Pentigan turning into Rick Astley, Tagg cosplaying as Gordon Freeman.....
The Frillish and their father, King Jellicent.
Especially Hypotenuse the Unicorn. It's actually a pineapple.
How does Fool deal with Domino? First, by applying a frying pan directly to her head, drawing blood. Then, recovering the electric whip used on Hatbox and using it back on Domino. The better part? She likes it. The best part? She gets to keep it.
-Twirls the Electrowhip around with enthusiasm-
It's funny, awesome and disturbing all in one sick little package!
The fangirls draw graffiti over the walls of crossover shipping. It starts with this note and gets even more insane after that.
And A's Floatzel writes "The unamused victims were here" over it.
The Fans Wild Mass Guesses about the group. Including such gems as Luke being a woman, Anom's hair and beard changing colour whenever he's alone, and Cynthia being an older version of DS who travelled back in to make sure her past self would become the champion.
Abigail and Thresher getting stuck together by the latter's spikes temporarily.
Emolga's fangirl glee over the fact that she briefly met her idol, and that said idol stole the moon, Cresselia, Darkrai and a group of Clefairy back from her (after Emolga had previously stolen those things) and put them back in their proper places.
The various strange Pokémon Latias keeps trying to ask if they've seen the amulet or heard anything about the Delta Pokémon. Among other things, she encouters a group of Wingull that act just like the seagulls in Finding Nemo, some Slowpoke that don't even react to her until she's already left and a Houndoom trying to protect some Miltank from being abducted by aliens.
"To think that when I started writing the Fake!Shahinne scenes, my intention was simply to have the real one sleeping at the pillow fort, having forgotten about having casted Double Team." - Silentran♂.
Starting here, we have Crewe and Herbert meeting up at the Phenac Ice Cream Parlor where the two start out by bringing up their on-going dare to see who can wear something they normally wouldn't for the longest, which somehow ends up involving the two of them agreeing to see which of them can get through the tests to join PEFE faster, and it gets even weirder from there, to the point where even Eskay is weirded out by it!
Kyrie and Rembrandt spontaneously bursting out into Bohemian Rhapsody.
