I feel like this also implies that rome is somehow being destroyed by the end of the day

The Emperor Constantine loves Finius and Ferbingetorix's "New Rome" so much that he makes it his new capital and names it after himself.

Yeah that checks out.

What's the doofenschmirtz contraption/scheme of the day?

Doofenric the Ostrogoth (insert jokes about his daughter Vanessa being "Goth" but in the modern sense) invented a City-Mover-Inator to move Rome across the Danube so his Germanic confederation could sack it.

Thankfully, Agent Pericles stops him by redirecting the Inator to Finius and Ferbingetorix's New Rome instead, moving it to the Bosphorus.

While Pericles and Doofenric are fighting over the controls of the Inator, it gets accidentally changed to paint remover mode and then fired at a random direction.

Somewhere nearby a painter just finished coloring the statue of the emperor when suddenly all the paint gets removed.

Painter: Aw...

Painter, giving it a second look: Hmmm... 🤔

Candysseia: What animal even is Pericles?

Finius: We named it "platypus", meaning flat-foot.

Ferbingetorix: On account of his feet being flat.

Candysseia: And where did he come from?

Febingetorix: We have no earthly idea.

Doofenric the Goth: Pericles the- wait, what animal even are you, Agent Pericles?

Pericles: *hands him papyrus*

Doofenric: *reading* A "platypus", meaning flat-foot... oh, on account of your feet being flat!

To be clear, the Emperor Constantine looks like Roger Doofenshmirtz.

Also, I agree with everybody who says that Greco-Roman Candace's name should be Candassandra (since nobody believes her warnings).
