Answer:
To cross the water I'm the way. For water I'm above I touch it not and truth to say I neither swim nor move.
I am flora not fauna. I am foliage not trees. I am shrubbery not grass.
I can swim but never get wet. I can run but never get tired. I follow you everywhere but never say a word. What am I?
I am the kind of nut that is empty at the center and has no shell.
What gets whiter the dirtier it gets?
I am owned by Old McDonald.
