(This isn't part of the vote, but here's all the references in Starhunt!)
Chapter 1: Undertale refrence at the start of the chapter in the 1st comment as well as a Skylanders, Nintendo Switch and Animal Crossing reference.
Chapter 4: A reference to "the matrix" (kinda)
Chapter 6: Mayu drops an s word bomb
Chapter 7: Mayu uses the word "pecking", which is a swear word in A hat in time.
Chapter 8: Scout mentions a teacher with a bald head and a ruler. Pretty obvious what she means by that.
Chapter 9: Chill, Heat and Huge Guy are basically a refrence to the members of Deep Cut from splatoon. Oyster is a reference to Pearl from Splatoon as well. Make-A-Grizz is a Build-A-Bear reference.
