In the winter i am thin. In the summer i am thick. I can get really old, and you need me to live. What am i?

There’s a man inside of me I swear I did not eat, Though I do come from a carnivorous species that’s extinct I stole from Yankee Doodle a very catchy melody But despite the rumors, I’ve done no crime, I’m part of your family

I speak without a mouth, and move without feet. I’m born in silence, but die if you repeat. What am I?

I move from house to house, but I always stay outside. You can find me by the shore for my home is the tide.

I have whiskers and webbed feet, but I do not have flippers nor a lot of blubber. I am known for using stones as a 'clubber'..
