You ate a devil fruit which is called the "peto-peto fruit". A Cursed fruit that allows the user to control every living creature by giving them a green collar.

At this time , you were fighting with Law , Luffy and Chopper. As always , you gave them the green collars.

"Stop." Is just what you said and they stopped.. Law and Luffy was confused and furious. "Sit." , Law and Luffy sat like a dog.

Law: looks away

Luffy: What the!! Whats happening?!

Law: It's her fruit , Strawhat-ya.
