SMG4: There's Something Up With Meggy...

Sypnosis
Meggy's been acting really weird... and Mario + Luigi are caught in the middle of it!

Plot
The video starts with Luke Lerdwichagul and Kevin Lerdwichagul advertising their SMG4-Meta Runner crossover posters and shirts which are on sale until the release of Meta Runner on July 25, 2019.

The actual video starts in Peach's Castle. Luigi is watching TV, but goes outside after hearing drilling; he sees Meggy building a treehouse, the latter however, is still upset of the events of the Anime Arc. Luigi then reminds her that she should be training for Splatfest, but this causes Meggy to remember Desti's last words, and when Luigi asks Meggy if she's feeling O.K., she instead throws him out of the treehouse and starts to work on it crazily.

Luigi then brings his brother to try and solve the situation, only for him to wreck the treehouse; this causes Meggy to go insane and chases them into the castle.

Mario attempts to calm Meggy down by being friendly, only for him to be abducted by her. Horrified, Luigi runs up the stairs and stumbles upon Tari playing video games. Meggy soon finds them, but when she sees Archibald (Tari's rubber duck), she becomes obsessed with it and pesters Tari to buy it from her, even resorting to use the castle's funds and live people, further deteriorating her mental health.

Mario, Luigi, and Tari find out that she was acting like that because of Desti's death, which results in a flashback from Mario as he was getting impatient since Meggy was trying to buy new clothes and noticed the sweater Desti wore on the rack of clothes. She then had a flashback of Desti first appearing in SMG4: If Mario Was In... Splatoon 2. When they attempt to calm Meggy down, the latter snaps out of her insanity and starts to weep, saying that she really misses Desti, and runs off.

The scene cuts to Meggy's house, where Mario, Luigi, and Tari arrive to find a weeping Meggy, and attempt comfort her, saying that winning Splatfest was Desti's dying wish. This works, however, backfires on the trio, because Meggy immediately dragged them off to train, even though Mario yells that Splatfest is ages away.
