This asset was used in one of my random animations back in 2010 and i decided to publish the source file (adobe flash ) animation  and the .png files as public domain!
Do whatever you want with it.

(im not sure if im allowed to upload .fla animations files in here since this is a "game related" website so i uploaded the full .zip file on my website)
