I believe the story is that initially the Fun Guy Pet was released with the name "Fun Guy." with the period, so it was quickly taken down and a 'new' pet was made available called "Fun Guy". The Pets are functionally the same, as far as I'm aware there shouldn't be any difference in Pedigree, Talents, Derby Abilities, etc.
The Asterisk denotes that the "Fun Guy." is an Exclusive Pet, much like the Deckathalon Pets. This means that you cannot get the Pet via Hatching, as KingsIsle probably wanted to stop the Pet from getting out into the playerbase, in favour of the Pet with the corrected name.
There are some other Pets that have a duplicate - I believe the
Owl Protege is one of them.
As for how the wiki should handle it - I'm personally in favour of just having a note on the Fun Guy's page explain the duplicate Pet. I don't think a separate page is really needed, but perhaps others might be in favour.
