Glitchy Rabbit, Functioning Heart provides examples of:
- Ascended Extra: The crocodile character that only appeared in the show's opening in the original trailer, who wasn't given an official name, appears with a much greater role in this fic, and is given the name Crocker.
- Ear Ache: Bun-Bun gets bitten in the ear by Crocker in chapter 5.
- Electronic Speech Impediment:
- Bun-Bun's voice is prone to stuttering rather often, due to being corrupted.
- The same thing also applies to Fibby after she transforms.
- Fighting from the Inside: This is how Bun-Bun regained control of his body.
- Gotta Get Your Head Together: Bun-Bun not only does this in chapter 1, after recovering from Alloy Boy's punch, but he also does this in chapter 3, while trying to break free from the Darkness' control.
- Imposter Forgot One Detail: Fibby's disguise actually looks very convincing... except that, unlike the real Pibby, her blind eye is covered in Bandages instead of an eye patch.
- Insane Troll Logic: Downplayed. Although some of the conclusions that Bun-Bun reaches aren't entirely unreasonable, they're still far from what most other people in the same situation would probably think.
- Neck Snap: Bun-Bun delivers one to himself whenever he's dealing with strong emotions, including anger. It's a warning that he's about to lose control of himself.
- Never Smile at a Crocodile: Crocker is a crocodile, and thanks to being corrupted, he's outright murderous.
- Perpetual-Motion Monster: Due to being corrupted, Bun-Bun doesn't need to eat or drink. That doesn't mean he CAN'T eat or drink, though.
- Spot the Impostor / Confronting Your Imposter: Happens with both Pibby and Fibby in chapter 10.
- Precision F-Strike: One courtesy of Bun-Bun in chapter 10, after Fibby leaves:Bun-Bun: "WHAT TH3 FU-U-U-C-CK WA-A-AS TH-HAT-T-T-T-T?!"
