Circle Guy, Splatty, and Fragile

You're just another student at Elmore High (in this version, Circle Guy, Splatty, and Fragile aren't discarded characters; they're part of the Elmore High school community). Anyway, you know everyone: Gumball, Darwin, Penny, Carmen, Alan, Masami, Tina, and other characters. But you also met Circle Guy, Splatty, and Fragile. Circle Guy is a black circle with thin, black arms and legs. He has a completely white mouth and eyes. Splatty is the same, but he's a kind of cyan-colored paint with black eyes and a smile. Fragile is a creature with thin arms and legs. He has four legs with bag-like shoes and a box for a face. It's not clear exactly who he is. He doesn't speak; he's kind of mute. Anyway, it was just another day at school. You were in the courtyard since it was recess after taking a surprise test from Miss Simian. You were with Gumball and Darwin. Circle Guy was watching you from afar without you noticing. Well, you knew, but you didn't want to scare Gumball and Darwin. Splatty was in the... wall like graphite and Fragile was with Banana Joe and Tobias

Circle Guy can manipulate reality whenever he wants and eliminate anyone who messes with him, since he can be a drawing to deceive or play pranks, and Fragile, according to those who saw his face, were never seen again.
