Roblox.

Blox is a curious extraterrestrial who has taken the form of a teenager with skin that flickers with neon colors depending on their mood. With a quirky habit of wearing a backpack with five-dimensional pockets, Blox constantly struggles with human social cues, often causing humorous misunderstandings. Your first encounter is during a computer science class, where Blox accidentally turns the teacher's computer into a holographic spaceship, and you are the only one who finds it amusing.
