SMG4: Mario's Spicy Day 🔥 is the twenty-third episode of Season 10 and the five hundred and seventy-seventh overall to be uploaded by SMG4.
Mario is invited to SMG3's new production studio to star on his newest show, Spicy Ones. What will happen when SMG4 catches wind of this?
The episode starts with Mario, walking in the dark and wondering where he was. Just then, it was revealed that SMG3 invited him, welcoming him to his newly-built studio, Snitch Productions (parallel to Luke Lerdwichagul's real-life animation studio Glitch Productions), showing him around the stages and sets he prepared for content to be released on YouTube. SMG3 revealed that he started his studio after the cancellation of Dr. SMG3 on MKTV, and making an insult to his rival's other studio, and kindly showed him the spaghetti that he promised to Mario, which was placed on a table in a set for his web show, Spicy Ones, where he officially invited Mario as a guest.
Meanwhile, back at Peach's Castle, SMG4 stumbled across SMG3's video on YouTube, and proceeded to watch it, looking at Mario's antics. Although pessimistic, he was shocked to see that the video had gained popularity, along with mocking comments about him and praising comments to the video. Believing to be another of his evil plans, he sets out to stop him.
At the studio, it was shown that SMG3 and Mario are getting along with each other, and proceeded to shoot the next video. That was during the shooting that a shadowy figure appeared right above the set of SMG3's Puzzle Palooza, revealed to be SMG4 as Mario recognized him, and fell down. Trying to get Mario to stop him from his "evil plan" failed, so he got chased by the studio's security, destroying the sets on his way. His chase had also angered the short-tempered Isabelle and Sans, who were doing their podcast, and in a fit of rage, they destroyed the whole studio, killing themselves and others during the impact, safe for Mario, SMG4 and SMG3.
The studio, now reduced to ruins, as Mario and SMG4 walked up to SMG3, sad that everything he had built for was gone. As SMG4 continued to mock him about his another bout of failure, SMG3 revealed that he never had an 'evil plan' after all, and lashed out his hatred of him ever since they went to meme college, where he was pushed over by the latter's popularity. Seeing how that turned SMG3 into the state he is currently now, he tried to apologize to him, but was quickly rejected, and SMG3 had finally enough and declared that he will come back again, now truly evil, as the world really sees him. He disappeared into the thick smoke, but then only came back to give a groin kick to SMG4, ending the episode.
