On a rooftop nearby…

"There's not much to see here, Batman."

"Then perhaps we need a closer look."

The Penguin has always been careful to avoid unwanted attention. All the windows are tinted black. As they watch, one of the Penguin's men leaves the premises, allowing the flashing lights and thumping bass to spill out on to the street.

"But why would the Riddler direct us to the Penguin's hideout?"

"I don't know Robin, but I'm going to find out."

"We can't just barge in, can we?"

"Not without suspicious circumstances."

"All I see is a nightclub playing loud music to a crowd of people."

"At twelve o'clock. Noon."

Without another word, the dynamic duo leaps into action. Swinging down from the rooftop they crash through the window of the nightclub in fantastic fashion and alight safely on the dance floor. Just as Batman suspected, there are no revellers or patrons in sight.

From the office, the plump pilferer appears, gesturing wildly with his ubiquitous umbrella. His eyes open so wide his monocle falls from his face.

"What, Batman? Already?" the flustered fiend remarks. "You nocturnal nuisance! Aren't you up past your bedtime?"

"Justice never sleeps, Penguin."

"Then we'll just have to lay you to rest," Penguin squawks. "Kill him!"

The liveried louts posing as waiters charge at the vigilantes, but these partners in crime-fighting are more than prepared. Bang! Pow! Before long, their assailants are disabled and only the mastermind himself is left.

"This will ruffle his feathers!" Robin announces.

In a dazzling display of aerial acrobatics, the Boy Wonder launches himself at the old buzzard, performing a triple twist in mid-air before delivering a kick to the bird's plump belly. Penguin's top hat topples and the crime boss flattens it as he falls.

"That took the wind out of him," Robin declares cheerily as the Penguin gasps for air.

"Luckily," Penguin wheezes. "I always get a second wind."

Using his infamous trick umbrella, he releases a cloud of noxious gas. Robin reels and falls to the floor unconscious.

"You can nurse your bird to health, or stay on my tail feathers. Your choice Batman."

With that, the conniving coot waddles away. His plans are still a mystery, the Riddler's involvement a conundrum and now Robin, the stalwart sidekick is in peril. The choice is clear. Batman must cure his companion.

If only he knows how!
