Roonbulus is the pairing between Rhombulus and Queen Moon.
Season 3 Edit
- Butterfly Trap - When asked by the Truth Cube, Rhombulus reveals his crush is on Queen Moon, and Moon doesn't seem entirely bothered by this, though she is currently married and that would be straight up cheating.
Canon Probability Edit
This will never happen because Queen Moon is married to River, unless something were to happen to River.
