They may be small but these creatures have made a big impact. MSN UK News is proud to introduce Conchita and the mini-pigs. Conchita is a white-naped mangabey monkey, who currently resides at London Zoo. She’s only the second white-naped mangabey to be born in the UK. The mini-pigs are a new breed known as the Pennywell Miniature.  The petite porkers are the result of a 14-year breeding programme and they grow only to the size of a springer spaniel. The old adage that the best things come in little packages appears to be standing the test of time.
