Of all the times for there to be a noise, why in the middle of the night? It wasn't like it mattered, anyway. All of the Smashers present in the mansion were having an unfortunate case of insomnia, thanks to Samus and Kirby accidentally combining sugar and coffee, and then distributing it to the rest of the Smashers at dinner. Still, Mario and Pikachu were bothered by the sound at the door, and went to the mansion door to get to the bottom of it.
Mario was split between himself when he opened the door. On one hand, he liked to see that his brother Luigi had made the trip. On the other hand, he was a little annoyed that his brother was getting sleep and that he wasn't. Pikachu on the other hand, was annoyed at the pink puff ball that Luigi was sleeping next to. "Why Jigglypuff, why?" murmured Pikachu. Soon after, Mario and Pikachu began bringing the two slumber heads into the mansion.
Luigi knew two things. One, he needed to invest in some earmuffs. Two, he was in the Smash Mansion. The second he woke, up, he immediately explained how the two smashers arrived earlier, but were put to sleep (AGAIN) by Jigglypuff's singing. Apparently, Jigglypuff was so tired at that point even she succumbed to her voice. With that out of the way, the Smashers (seeing no reason to go to bed due to their insomnia) decided to get Luigi and Jigglypuff situated.
It was moments before midnight, but the Smashers still weren't sleeping. If only Jigglypuff could put us to sleep like Luigi, thought Samus. Then, a light bulb went off. Samus dashed to get Smashers around the mansion (which isn't easy in a Power Suit). Once all of them were grouped together, Samus ordered Jigglypuff to sing. Jigglypuff happily obliged, and within a few seconds, Luigi was out cold. The rest of the Smashers... were not.
Samus groaned in defeat, just as Luigi shrugged off his impromptu nap. It was as if nothing could get the Smashers to snooze. Mario then pipped in, declaring, "10-Way Smash, anyone?" At first, everyone gave Mario a weird look. Sure, he was Nintendo's mascot and everything, but his idea was just, oh I don't know, CRAZY! Before anyone could reject the idea, Luigi ran up to his brother, executed his Super Jump Punch, and randomly yelled, "SHORYUKEN!" Thus, the madness began...
Cue the 15 minute fast-forward. The Smashers looked about ready to clock out after the battle. Between his wheezing, Kirby ordered Jigglypuff to sing again. This time, even Luigi wasn't knocked out! The Smashers groaned. Was their insomnia too powerful, even for them? Were they to resign to this twisted form of defeat? None of these questions were answered, because suddenly, Crazy Hand appeared out of nowhere!
"OH, HELLO, SMASHERS! I just gotta say, you should really make this place easier to find! IT'S JUST TOO CONFUUUUUSING!" Crazy Hand bellowed his madness with a cackle. Sleep deprivation was probably infecting the Smashers' minds, as huge grins appeared in their faces. Crazy Hand looked at them weird (however hands looked). Suddenly, Donkey Kong screeched, "GET HIM!" The Smashers bounded towards the mentally insane hand, with their eyes in a glazed flame...
Cue the fast-forward cliche, again. The Smashers were still at it with Crazy Hand, unable to contain their desire to be tired. "Oh for the love of the void, would you just GO TO SLEEP!" Crazy Hand screamed! That was a big mistake on his part, because as soon as Jigglypuff struck his musical tune, Crazy Hand fell to the floor with a "BANG!" It didn't make the Smashers sleep, but the "BANG!" was enough to wake Master Hand.
"WHAT IS THE MEANING OF THIS?" Master Hand bellowed. The Smashers tried explaining all at once, resulting in incoherent babble. Master Hand snapped his fingers, demanding silence. When the dazed Smashers cleared their heads, it dawned upon them that they might have taken the whole thing a little too far. Everyone turned to Jigglypuff. "One more time, Jigglypuff," Fox ordered. Before the puff could begins it's melodic song, midnight struck, and all of the Smashers (Jigglypuff included) conked out, which isn't surprising between the coffee/sugar crash and the long, LONG night. Master Hand sighed, teleported the Smashers to their rooms (PJs on), and carried his brother to their room.
