Hmmm. Only dolphins can make dolphins.

Maybe you mean a navigation aid:

A Can Buoy marks the right side of the channel Leaving a harbor. It will be Green and have odd numbers on it.
Green Daymarkers are often used in shallow areas for the same purpose.

If the green marker has several pilings supporting it, it will be called a Dolphin.

Green Buoys with lights will usually be found in deeper waters.
