So in the episode, Beast Boy was about to hibernate, so the Titans took him to the Bat Cave, but Starfire yelled at him, so hibernation was now out the window. So Robin showed them around the Bat Cave (and Wayne Manor, since they found it), and his room. He wanted a Bell Biv DeVoe poster, but he didn't want any money to buy it, since he said, and I quote, "Money is a vice!" However, they convinced him to spend some money, which lead to a bunch of criminals attacking and stealing everything. Then Alfred came and defeated them all. I wasn't really interested in the episode, except for the part where they mentioned Bell Biv DeVoe.
Credit to all!
