Also, Plan 10 hints that Kraang Prime will be the main villain of "that which is known as the season 2 finale of the show which is called TMNT 2012". I am actually glad about the shapeshifting. Plus, there was an ORANGE substance that fell into the mutagen vat. Mybey that was som incomplete Retromutegen that Baxter had managed to make. That might be why she was able to (mostly) shapeshift back to her human form.
