I am a sound made by felines when petted.
I can sizzle like bacon, I am made with an egg. I peel layers like onions, but still remain whole. I can be long, like a flagpole, yet fit in a hole. What am I?
I am round. I have only one line. Circle is not my name indeed. What am I?
What do you get when you cross a snowman with a vampire?
I turn around once. What is out will not get in. I turn around again. What is in will not get out.
I go in hard, come out soft. Blow me hard and I'll make a pop. What am I?
