When their penguin pal Benji won’t believe they’ve travelled through time, Pablo and Splash have a point to prove. The two travel to Ancient Rome, hoping to bring back a centurion helmet as proof of their adventures. But when Pablo and Splash meet an emperor with a passion for collecting exotic birds, only some quick thinking - and emergency time travel - can save them from the fate that awaits them in the Colosseum!
