The trash cans are overflowing and there are still a lot of empty boxes to throw away. Kobe decides that the only way to make everything fit, is to crush all of the junk in the cans. Unfortunately pushing it down with her hands won’t work, so she puts her whole body inside and use all of her weight.
Both of her feet march and stomp so that she can make the other boxes fit inside. When the first round of boxes is mashed, she grabs the cardboard from outside of the bin and jumps up and down on them as well. Looks like everything finally fit!
