I've heard there are troubles of more than one kind.

Some come from ahead, some come from behind. But I've brought a big bat. I'm already you see. Now my troubles are going to have troubles with me! Given the rhyming scheme there is only one person who could have written this quote-Dr. Seuss, of course! The concept of this quote is quite clear but of what is made the bat my troubles fear? Remember, the hard part is finding the bat.
