Batman Unlimited: Mechs vs. Mutants

Damian Wayne, the new Robin (comics), is upset by his failure at trying to stop Joker (character) the previous evening, making his humiliation of falling off a building and having to be saved by Batman worse because it was caught by a video blogger and posted on the World Wide Web. Alfred Pennyworth tries to assure him that he's still learning, though Damian wishes he could talk to someone else who has been through the Robin training as Tim Drake is away with his team. Batman arrives as Damian is studying Batman's enemies, and comes across Penguin (comics), who he has never met.
