Here’s a solution with all requirements. Equip the Calligraphy Brush, Ink Shadow and Parchment background. Go to Party Mode, then Team Arcade. Trick the Kinect into thinking you have a second player next to you with a jacket or something more human looking. It took me a few minutes of going in and out of camera range with my jacket buddy but it eventually worked. You basically have to swipe Ready with your hand and then flail the jacket arms around to swipe Ready for the “second player”. You’ll notice that your swipe is red, whereas your dummy player’s swipe is blue. So if it swipes red with the jacket/object, it’s still only reading you as one player. After it starts the game, drop the jacket and get a 10 fruit combo, most easily done during a freeze or frenzy. Then pop goes the achievement!
It’s also worth mentioning that your equipped items might not show up during a party game. However it is required that you equip them in the dojo prior to playing. Those requirements only show up in the 360 achievements menu. I can confirm that playing without equipping these items first prevents a 10 fruit combo from unlocking the achievement.
