"It's an Orange Aardvark!" by Michael Hall

When the carpenter ants start drilling holes in their stump they're sure they've been discovered by an orange aardvark who quickly causes panic to ensue. Each new hole the ants drill to get a better idea of what the aardvark is up to causes more and more concern and possibilities as more and more colors are discovered outside of their bore holes. This is a really cute and imaginative book, with actual holes cut of the pages so kids can experience the thrill of discovery of the unknown with the ants.
