I can sway with the water flow and breathe through my body. Who am I?

I am fat, plump and thorny. I can dig deep to quench my thirst. Who am I?

I can fight the strong winds and handle the salty water. I remain green all year round. Who am I?

I have leaves like your dishes, I have stems like your plastic ball. Who am I?

I can't breathe in this pool of mud, I need to stretch out. Who am I?

I am your buddy and you can't live without me. Plants throw me out while you let me in. Who am I?

I am the van you are looking for. I will take you to your destination. I go both ways and help you out. Who am I?

I look like your birthday cap. I come with Santa Claus. I can fight the freezing cold and never dry out. Who am I?

I hold you and quench your thirst while I am afraid of the Sun. Who am I?
