Searching for Whos in a Field of Clovers

"That bird let that clover drop somewhere inside / Of a great patch of clovers, a hundred miles wide! / I'll find it. I'll find it! I'll find it or bust! / I shall find my friends on their small speck of dust. / Yes clover by clover by clover with care / I'll listen and I'll call, are you there? Are you there? / Are you there? Are you there?"

This is similar to what I picture as the field of clovers where Horton embarks on his futile quest to find the clover with the Whos living on it.
