What is the difference between natural and inverted sentences?

Natural sentences are when the subject comes before the verb. For example: The baby kangaroo hides in its mother's pouch. The subject is kangaroo and the verb is hides. Kangaroo comes before hides so the sentence is natural. An inverted sentence is when the verb comes before the subject. An example is In its mother's pouch hides the baby kangaroo. The subject is kangaroo and the verb is hides. The verb comes before the subject. So this sentence is an inverted sentence.
