I noticed in Steven’s closet in “Tiger Millionaire” you can see his puffy jacket from “Arcade Mania”, as well as the hoodie and birdie boots from “Frybo” (the boots were also in “Tiger Millionaire”). Also, he has multiples of his pink + star shirt.
There’s just something about cartoons thinking about where characters get their clothes and changing it up and stuff that I really, really like.
Also, there’s a rock on his shelf. Maybe Garnet always bring back rocks for him.
