The 47 uses of mud!
Ok I this issue we got a plenty introduction of Clayface, starting by Plasmus stepping in a way full of mud saying it remembers he his friend Clayface, we see the "way full of mud" is the track Clayface is leaving and that is being cleaned by Brainiac 5 who uses it like a example for experiments or something alike.
Then we see that Plasmus made a team subdivision called "Squishy Titans", Plasmus say that Clayface is made of clay and mud he hows them the use of clay ( in shape-shifting) and Robin asks the "One-hundred million dollars question" "What can you do with mud?" And Clayface answers with some of it's many uses (47 as I counted) then he "gave" some mud to everybody and got washed and pulled himself together again (Weird like Aqualad says)
And some time after Plasmus got a "Cheese log" from a secret admirer and thinks is Glomulus, who is actually eating all their food, Bumblebee is revealed as the secret admirer and kisses Plasmus (D'aaaw)
Oh and you can see Robin and Aqualad talking about that all superheros changed their costumes (obvious reference to DCnU)
My favourite part: (Look at that WTF face of Larfleeze)
