The grinch is not happy about Christmas and of course sets out to ruin Christmas for all of Whoville. But once the Grinch comes down this Chimney she discovers a bunch of Christmas balloons she finds especially horrid. So she destroys every single balloon in every which way. The Grinch foot pops them, nail pops them, squeezes them, bite them, Pinwheel pops them and in the end us quite satisfied with the mess she's left.
