Dead memes tell no tales ☠️
The episode starts at Mario's House, where Luigi is seen relaxing while listening to music on his AirPods, until the Content ID showed up, abducting him and taking him to the Internet Graveyard, where he meets Mario and a mysterious person, who Mario correctly thought of him as Axol, before the latter started attacking the brothers. After a lengthy confrontation, Mario tried to unleash the Naruto Run on him, making Axol regain his memories.
As Axol went sane, he told his story of how he got there, as a result of Mario summoning the Content-ID three weeks prior, breaking Inkweaver upon arrival and making him insane because of all of the dead memes that live in this realm. As Mario lamented on the broken Inkweaver, they were suddenly ambushed by a colony of Ugandan Knuckles trying to take them away, but however they managed to escape when Axol fed them Tide Pods (although Mario had some too).
After showing his handmade anime to the brothers and showing a bout of insanity, Mario asked about a way to get home, until Axol only mentioning one way to get, in which it needed to make a dead meme relevant again, however it is impossible. Luckily, Mario knows someone who is good at this, and the guy is apparently SMG4, who is an expert on memes. However, since there is no reception in the Internet Graveyard, they need to adventure to a Starbucks Coffee near the realm's temple to get Wi-Fi, with scenes showing their adventure.
After for sometime, they arrived at the temple, where they were quickly denied by the lords of the temple for access to the Starbucks, but eventually they were allowed to thanks to Mario fixing their toilet with his plumbing skills. However, the toilet suddenly plunged out, hitting Pingas, leading to a chase.
Mario, Luigi, and Axol managed to get into Starbucks, and thanks to the Wi-Fi signal, Mario was able to call SMG4 on his iPhone for help, thus enabling him to revive a dead meme. SMG4, with Mario's suggestion, with his meme trading skills with some help from Meggy and Bob, managed to get a meme, Harambe, summoned, allowing the three to escape the Internet Graveyard.
Once back in SMG4's room, SMG4 tried to ask about how they got there. Basically, Mario knew everything from the start, but had to go for a toilet break first. Wondering where Harambe is, the rest saw him flying out to the sky, with the three admiring him flying into the sunset as the episode ends.
