Everyone knows pumpkin pie just isn't the same without a giant dollop of whipped cream. Draw vertical or horizontal lines to match each serving of pie with that delicious dose of sugar.

* Each dollop of whipped cream must connect to only one slice of pie, and vice versa.

* Connection lines may not cross each other.

(The answer checker only recognizes normal green lines as part of the solution.)
