PowerPoint animates Halloween!

Ghosts float. Bats flutter.
And with PowerPoint animation and Microsoft clip art, teachers can create a short, silly, and not-too-scary PowerPoint holiday greetings for impressionable little goblins.
Here is a 3-slide, 17-second
Halloween PowerPoint greeting featuring a grinning skeleton, fluttering bats, flying ghosts, an anxious pumpkin, a grinning witch -- and a jazzy soundtrack. How can you edit this animated PowerPoint file to make your own unique Halloween greeting?
Will you make the skeleton wave? The witch cackle? The ghouls moan?
Even if you are not presenting to tots, how else do you plan to dress up your October 31 presentations? What will you wear? And what special treats will you bring for your audience?
