Star vs the forces of evil (trial by squire)
The store clerk asks Star and Marco if they really meant to grab "two of these defective happy gnomes". To this they say "Yes. Yes we did." which refers to something completely different.
Could I also put this in the trivia section for Gnomes or is that only for in-universe trivia?
Hello, and for me yes, cause they absolutely look like the gnomes from Gravity Falls.
Um, no. That's not a reference; that's just how gnomes look. It may be a case of the SVTFOE crew taking "inspiration" from GF, but we have no proof of that.
That gnome on the right has the exact same color scheme as the ones from the show, and otherwise is pretty much the exact same character model as the ones from the show, apart from slight stylistic difference and missing eyebrows. This is definitely a gf reference.
Haven't seen the episode, but I would say that, unless there are other GF references in it that could connect to this, or there's some dialogue that suggests it's a reference (like "why would you draw gnomes like this?" or something), then I would just chalk it up to the shows having similar animation styles and that just being a common way to draw gnomes.
Actually the show never draws characters with exactly round eyes that touch in the middle, and without pupils. This is directly taken from the gravity falls art style. Why would you need aknowledgement of the characters to see it as a reference? It's just a little easter egg for eagle-eyed viewers, it doesn't need to be adressed in the show itself.
