It was "PonFormaTortuga", which means the same thing as PonForma, the translation for BITMAPTURTLE. It doesn't make sense that "ponforma" should mean both bitmap the turtle and remove the bitmap. To correct this, I chose an opposite of "pon", which is "quita". The strange "PonFormaTortuga" was added by COPYDEF for backward compatibility. It may be removed in a future version.
