- When in Rome... - The Oracle, wishing to test the Underground's practical capabilities, strips them of their powers and sends them into an alternate, Roman-themed reality where a Sleet look-alike named Sleetus presides as King. The former fast and furious hedgehogs must use their usual blend of cunning and strategy to save this reality, but without their abilities, will they be stopped dead in their tracks?
