Alliteration By Oliver

Hi my name is Oliver and I'm going to show you how to do alliteration.
This is how you do it.

An armoured armadillo avoiding an angry alligator. See all those letters start with A but occasionally you have to use a little word such as and.
I will do other alliteration sentences.
