what am I?

Remember this stretchy post?  Remember those ‘What am I?’ riddles I told you about?

Well, if you haven’t yet had a chance to look for yourself, here is something to whet your appetite.

I am round, light and floaty

I sound like an elephant trumpeting, a police siren

Watch me whizzing, squeaking, spitting

You find me at birthdays

What am I?

I am bouncy, yellow and round

I sound like a baby crying, someone screaming

Watch me bouncing, bursting, rolling

You find me at parties

What am I?

I am round, bouncy and floaty

I sound like an elephant trumpeting

Watch me popping, squeaking, flying

You find me at parties

What am I?
