After the gang went back to Peach's castle, SMG4 asked, 'What is this place?' 'It's your home—Peach's castle,' answered Tari. She then tours SMG4 through the place. 'Well, this is a familiar place, but it is a blurry memory for me,' exclaimed SMG4. Luckily, everyone helped him to memorise more about this 'blurry and familiar' place, and reintroduced themselves to him.
Thanks for the gang's help, SMG4 slowly remembers the gang members and the whole castle. Later, the gang slowly forgot that SMG4 was memory loss and a month later everyone was doing their own stuff as usual.
However, Luigi, who was in the castle garden, spotted and thought that something was wrong with the SMG4 earlier. He wasn't making memes anymore since he forgot that he is a meme maker. Also, he preferred to go outside for a walk instead of staying inside with his computer. He spotted that nearly everyone didn't notice the problem.
Just as the green plumber wanted to tell someone about that, Tari and Boopkins came in the garden. Tari told him, 'I spotted something weird to SMG4. When he goes out for a walk, his face expression is often worried.' 'Also, I spotted that SMG4 was just playing video games instead of making memes,' added Boopkins. Luigi, then, told the duo what he discovered.
'Well, we should tell everyone about that!' Suggested Boopkins. Luigi and Tari agreed as they walked out of the garden.
