Answer:
I go up, let out a load and then go back down. What am I?
I have a strong affection for belly buttons.
I am the signature stroll of ducks and penguins
I can fly but I have no wings. I can cry but I have no eyes. Wherever I go darkness follows me.
I am the only word that looks the same when spelled upside down.
My first is snapping, snarling, growling, My second's industrious, romping, and prowling. Higgledy piggledy Here we lie, picked and plucked, and put in a pie.
