Saving the Villains

So, Joker, Two-Face and Riddler went missing from the superheroes and playsets the boys got for Christmas aka "Superhero City" (which used to be our living room). I looked all over for more than an hour, couldn't find them. The boys denied all knowledge. Finally, I said "Boys, let's find Joker so we can fight him!" Luke took me right to his hiding spot where all 3 were. When asked why he hid them, "I was saving them from the superheroes". Saving the bad guys!! That'd worry me...but then again, Eli snatches ANY villain that sets foot in his city and tosses them in the Batcave jail. There's about 10 guys stuffed in there on top of each other right now.
