Here ya go guys. Try them out and have fun. However please do not put Pig in any Youtube videos. She is meant for you to just see her animations and where she's going. She's not ready for playing. Tom on the other hand should be fine for videos.
About Compressed Archive Formats Compressed archives combine multiple files into a single file to make them easier to transport or save on diskspace. Archiving software may also provide options for encryption, file spanning, checksums, self-extraction, and self-installation. Zip is the most-widely used format, used by the Windows operating system and more recently by OSX as well.
