Its might be Panda... who knows.
:)
Because Penda will sounds like Пинда in Bulgarian....which is not correct again.

I should write yesterday, when I saw your post for Martentitsa....and the story.
In fact, Grandmother Marta, is not correct - should be Grandafather Mart...because...the god of War Marz...which is before Khan Asparuh and the tradition is probably before Asparuh.... but this is not so commerce and romantic.
