What kind of art is it when you...?

What category of art is it when you take something and turn it into something completely opposite? Like sculpting a pirate ship made out of candy hearts and rainbows with unicorns steering the ship. I'm filling Mozzarella with Co2 and making them into "Balloons", however I want to categorize it under an actual subject like Art Decco or Contemporary, not just "looks good dude"
