Answer:
I build bridges of silver and crowns of gold. What am I?
you hold my tail while I fish for you
I go from house to house a messenger small and tight. Whether it rains or snows I sleep outside at night.
My first is in some but not in all. My second is in tiny but not in tall. My third in little but no in big. My fourth in port but not in pig. My whole is made in nature's way. For clothing rugs used every day.
Who keeps the ocean clean?
Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
