>>99333194>>99333298>This show is not about muh lore or epic plot, its about the charactersThat isn't wrong but it's a pretty dishonest way of stating it. This is definitely a character-driven show and personal drama between characters carries a lot of the story's emotional weight, but there are still plenty of story arcs that are carried between episodes across the entire cast.
Not seeing Buff Frog's perspective on why the monsters chose to leave wasn't because "this is a show about characters not the monster plot," the decision was simply made to focus on Star and Tom's relationship at this time instead. The episode itself is named after another episode that was told from Buff Frog's perspective; he has been used as the "monster perspective" character since Mewnipendence Day and is a major supporting character, certainly there's no question he's considered a viable character to lead an episode.
If I had to speculate this episode was just a case of the writers/boarders maybe leaning too hard on the "show, don't tell" thing again, knowing that with wherever the story is going we don't need to know why the monsters left, and instead choosing to return the focus to a plotline that will be more relevant sooner.
Presumably the Tomstar/Starco conflict will flare up again in "Booth Buddies" following up on the friction established in "Monster Bash" and "Stump Day," while the narrative purpose of the monsters leaving may not be clear for a longer time and the explanation why, if any, we may not need to know.
Additionally, this season and this half in particular has been back-to-back storylines with episodes flowing right into each other, and this structuring makes it more difficult to find the time and place to express character development within the storylines they want to tell. So to contrast the Starco episode (Marco Jr.) before the progression deadline (Booth Buddies) the Tomstar episode has to step on the toes of the monster episode.
