Advertisement Adventure Time is off this week. As always - minor spoilers ahead! Steven Universe - "Cheeseburger Backpack" & "Together Breakfast"Steven Universe is back with two episodes this week. In the first episode, Steven attempts to show he is of some use, but only because he has a special cheeseburger backpack (a backpack shaped like a cheeseburger, not a backpack made of cheeseburgers or a backup with a never ending supply of hamburguesas). This week's second episode sees the cast dine on breakfast in the Temple of the Crystal Gems.Regular Show - "Bank Shot"Battles are fought and won on the court...well, the tiny court that accompanies the sports bar arcade basketball machine. Rigby gets a little cocky and bets a ton of money on his skills after a night of demolishing at bank shot.Teenage Mutant Ninja Turtles - "Mikey Gets Shellacne"This week, Michelangelo struggles with one of the worst maladies known to teens...acne. Will Mikey jump headfirst into a tub of benzoyl peroxide to rid himself of these mutagen-induced boils?Legend of Korra - "Night of a Thousand Stars" & "Harmonic Convergence"Nickelodeon brings us two episodes of Korra as the season raps up next weekend. Republic City is under attack, putting President Raiko in danger, while Korra seeks to close the doorways to the spirit world before a devastating convergence occurs.Avengers Assemble - "In Deep"Back from the dead, Avengers Assemble returns this week with a tale of infiltration and espionage as Iron Man and Captain America don new identities to sneak into the Red Skull's inner circle.Hulk and the Agents of S.M.A.S.H. - "Into the Negative Zone"A new spin on a classic Hulk/Thing team-up!
