Dorf(VYM024) was born in the Young Ones Mob on Janaury 21, 1998. His mother was Morgause and his father was Keros, the dominant pair of the Young Ones. Dorf was born in a litter of three, his litter-mates were Hunca Munca(VYF023) and Moppet (VYM025). All three pups survived their first year and reached adulthood. Dorf helped out around the mob with the pups and sentry post, he also soon started to take an interest in roving. In April 1999, Dorf's sister Hunca Munca gave birth to a litter of three pups. Dorf and his brother Moppet stayed in the Young Ones till late 2001 when they left with some other Young Ones males to go roving.
The males came across another mobt known as the Vivian Mob and joined the mob after most of the adult males had taken to roving. Dorf did not become the dominant male and soon left with Moppet and another male named Pippin in mid 2002.
The three males soon joined the Frisky Mob which were in the same situation as the Vivian. Pippin was older so he became the dominant male. Dorf remained in the Frisky for a little over a year till he disappeared and was Last Seen on November 25, 2003.
