Team up with friends to complete elite levels. You use Milk Biscuit Man as your meat shield, and he chooses Snow Cheese Biscuit Man to output. As a result, he pressed the wrong skill too fast, and the laser hit your unshackled shield. After bouncing back, he strung a group of zombies into "Tomatoes on sticks". The two of them stared at the falling gems on the screen and laughed, turning the mistake into a "hidden combo".
