A new level kit and costume pack based around Spongebob Squarepants are both making their way on the PlayStation Store today! With several characters from the underwater-set cartoon to dress up as, including Spongebob, Patrick, and Gary, plus an assortment of content like stickers, decorations, and materials, including a special one titled ‘Floaty Fluid’ that finally offers up a water material whose form can be messed around with by creators.
More details can be found on the PlayStation Blog here, with a few pictures from StevenI’s article on the DLC shared below. You can chat about the bubbly new downloadable content in the comments below or in the forums thread for it by Toastrz from the shiny materials featured to the creepy face-mask-thingies included.
Game Update 1.19 for LittleBigPlanet 3 is also available as of a couple days ago, with details on all the fixes available here on the PlayStation Forums and discussion had here on Sackinima Forums (although most of it is just about the Spongebob DLC being leaked).
