R64: Revenge of Freddy's Spaghettria is the twenty-sixth episode of Season 5 and the two hundred and thirty-ninth overall to be uploaded by SMG4.
Yep The Mario bros are back and it appears there is still spaghetti inside an old spaghettria! oh boy! letsa gooo!
The video starts with everyone in Peach's Castle asleep except for one shadowy figure. As it snuck into SMG4's room and used his computer, SMG4 was awoken by the figure typing away on his computer. He tip-toed to the light to turn it on to discover that it was Mario in the nude looking at pictures of spaghetti. When SMG4 demanded to know Mario's reasoning, he claimed that he had to keep it a secret from Luigi who then revealed that he already knew about Mario's activities.
Trying to drag Mario away from the computer (while he was complaining that he had to do this because all the spaghetti shops were closed), the computer showed some spaghetti news about Freddy Fazbear's Pizza being closed but still having some spaghetti, much to Mario's joy. (Chica the Chicken thought it was pizza but Mario threw the monitor at her because she was wrong).
While driving to the restaurant, Luigi wondered why Mario took him, who responded that he was a sacrifice for the animatronics. Shocked, Luigi tried to get off but Mario revealed he already bolted the door from the outside, much to Luigi's horror. When they got there, Mario demanded Luigi to hurry up while Chica, who secretly stalked them, just stared at the two entered the restaurant.
Mario and Luigi, the latter who was holding a chainsaw in fear, enter the spaghetteria. While looking around and passing a sign that read that the spaghetteria was redesigned for Fazbear's Fright (setting the reference to Five Nights at Freddy's 3), Mario found a box filled with animatronic heads in the security office. Deciding to play a prank on Luigi, Mario wore a Bonnie Head to scare Luigi, who was passing by the office. The younger brother immediately screamed in fear as he exploded.
Outside of the restaurant, Chica was idly looking around for pizza when she noticed a Pizza Bros truck passing by. She jumped onto the windshield, scared the driver, and sent the truck flying to in front of the pizzeria door, causing it to block the pizzeria exit.
Mario was now looking inside the fridge of the office for spaghetti but he only found other stuff, such as a skull, a tube of Pingas Chips, and Old Man Hobo (who wanted food). Luigi became nervous and told Mario to just leave since there was no spaghetti. Mario was feeling discouraged, causing him to agree, making Luigi do a victory dance through the hallway when he bumped into Springtrap. Luigi became so scared that his head shrank, and Springtrap prepared to attack, only for Phantom Balloon Boy to come in, making Mario mad. Springtrap threatened to kill them, causing the Mario Bros. to attempt to make a break out of the pizzeria. As Mario tripped, he called for Luigi to help him out but Luigi ditched him, making Mario swear at him and get caught by Springtrap offscreen. As Luigi successfully made it to the front door, he tried to get through but due to the overturned pizza truck Chica caused (who was now eating the dropped pizza), he was blocked off from leaving.
Unable to escape and saddened that he and Mario got separated, Luigi suddenly heard the phone ring. He answered it but the caller's voice knocked down Luigi before hanging up. Suddenly, the phone started playing What Does The Fox Says?. Luigi relaxed and enjoyed the music, lowering his guard until suddenly, Phantom Fox appeared behind him, scaring him into exploding into a coin.
As Luigi (somehow he restored back to normal) tried escaping, Phantom Balloon Boy and Phantom Freddy appeared, causing Luigi to be surrounded. Having enough, Luigi took out his Poltergust 3000 and tried sucking in all the animatronics, succeeding with Balloon Boy (who got stuck in the nozzle) with the rest running away. Suddenly, Springtrap came in, shocking Luigi into trying to suck him to no avail. Springtrap laughed at Luigi's futile attempt just to get hit by Luigi throwing the Poltergust at him.
As Luigi was observing the cameras via a tablet, he noticed Springtrap getting close to the office he was him. Needing to deter him, Luigi pressed a button that played: "Let's play some Super Mario Pingas". Happy upon hearing such a sound (and to Luigi's joy), Springtrap started going around in joy. However, after pressing the button too many times, Luigi got an audio error. He quickly checked the cameras but it gave a video error. Then, a maintenance panel came up but Luigi accidentally shut it down (and blew it up for good measures). He then turned to realize that not only was Springtrap nearby and saw him, the ventilation also had an error. When Luigi turned to see if Springtrap was there, he also disappeared, causing Luigi to be shocked into thinking it was just a hallucination.
Luigi went spiritual, having lit candles in the room, an unknown symbol on the wall, and holding a cross, trying to dispel the "spirits" from the room. Just then, Springtrap appeared at the end of the hallway, right behind Luigi, and started chasing him again. Before he could get close enough, Phantom Foxy popped up out of nowhere and accidentally tripped Springtrap, making him hurt himself and continuously complain about the injury.
Luigi was glad to see Springtrap down for the count and started celebrating. Luigi then heard Mario's voice from another room and immediately followed it to find his separated brother. However, he received a shock when he saw that Mario was now in the form of a robot, Animatronic Mario. Luigi was getting nervous but then Mario activated a SPAGHETTI.EXE program and suddenly pictured Luigi as spaghetti. With that, Mario pulled out a rocket launcher and opened fired on Luigi, who didn't hesitate on making a immediate get away from the room. Mario continued attacking Luigi and chased him through the spaghetteria.
Luigi then saw his Poltergust with Phantom Balloon Boy still stuck in it, so he decided to go back and face Mario. Before Mario could fire at him, Luigi got out his clogged Poltergust and changed the setting from Suction to Blow, firing Phantom Balloon Boy at Mario, who took a direct hit. When he got back up, Mario was heavily damaged with a "critical error" but before he could do anything, Luigi got right up in his face and punched him, finishing Mario off as "SPAGHETTI.EXE HAS STOPPED WORKING".
Luigi was worried that Mario might have been down for good but he slowly got back up, glitching out a bit, and looked at Luigi before suddenly getting naked and dancing around, apparently back to his old self again. Luigi was relieved to have his brother back.
Springtrap hasn't moved from his spot, still complaining about the injury he got from when Phantom Foxy tripped him.
Mario started to leave the room, which made Luigi immediately interrogate him on where he was going. He told him that he was going to get his body back and warned him not to die as he set off. He teleported to the "Phantom Animatronics Lounge.", where the animatronics were relaxing. Mangle asked Phantom Bonnie what was the most annoying sound in the world before screaming, which caused Phantom Bonnie's head to explode.
It was also The Puppet's birthday, and then all of a sudden a notification popped up saying "Animatronic needed", so Phantom Freddy teleported to Luigi, popped up, and said: "Peek-ka-boo", which scared Luigi and caused him to explode. He then teleported back and presses a button labeled "easy" on it.
Mario then walked inside the lounge and went to Phantom Chica to ask for his body back, but Phantom Chica refused until he gave her 1 million pizzas. Mario told Phantom Chica to bring him to her boss but she still refused while still saying saying "Pizza," which caused Mario to dare her to "Say pizza again". Phantom Chica then spazzed out and kept saying "Pizza", enraging Mario into throwing her to Puppet's table which broke and caused his cake to fall on the floor, making him go crazy. Mario sneaked in while The Puppet threw a fit while Phantom Chica kept saying "Pizza". As he got into the back door, Mario saw a door labeled: ""Do not enter".
Mario entered the door anyway when he saw William Afton. William didn't program him to come back and also told Mario he wasn't getting his body back. To prove he did not have the program anymore, Mario got naked and started singing and dancing "lot'sa spaghetti", causing infinite number of spaghetti to swarm William. Not wanting to deal with Mario, he escaped down a pipe where on the other side, he saw Luigi. Naturally, Mario managed to catch up with him and tackled him. Claiming he would not be taken alive, William ran away, with Mario and Luigi in pursuit. William came across Springtrap, still complaining about his injury, and deactivated him. He then fused with Springtrap to become Super Springtrap. Unfortunately for him, the suit malfunctioned, killing him, with Mario congratulating him for dying.
Mario blew up the door with dynamite and then wondered where his body was. Then, his body (which was on fire) came flying out of nowhere. Then he said, "Oh there it is." After that, he picked it up and told Luigi he would get Professor E. Gadd to fix it. They then walked away from the pizzeria, which was now ablaze. At the end of the video, Chica appeared out of nowhere and starts singing "It's Getting Hot In Here" before screaming in pain.
