Answer:
I am a caribbean shape that makes ships disappear
I am seen in the water. If seen in the sky I am in the rainbow a jay's feather and lapis lazuli.
I am brown and sticky
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 neck but no head. I have a body but no arm. I have a bottom but no leg. What am I?
The more of me you take, the more I appear behind you. What am I?
