Answer:
I have wheels and flies yet I am not an aircraft.
My teeth help me suck.
I reach for the sky but clutch to the ground. Sometimes I leave but I am always around.
I am merry creature in pleasant time of year as in but certain seasons I sing that you can hear; And yet I'm made a by-word A very perfect mock; Compared to foolish persons And silliest of all folk.
I have a head and a tail but my eyes can never see my tail.
I'm the source of all emotion but I'm caged in a white prison.
