Magnus the Micro-Mutt was conceived in 1992 as a failed comic-strip adventure.  In any case, he was sensibly copyrighted in 1993.  Though his inception failed to interest the national newspapers at the time, the twins developed him as small children's books and of which were illustrated by themselves.  This spurred interest from a computer game Rep (then, CD Rom) but of which was dismissed on the grounds of the dog not being famous enough.  Due to the approach through promotion in the papers, this nonetheless encouraged Ronald & Philip to continue with Magnus, even today.  He has had several revamps at this time and they are looking to publishing him in an old adventure based on Mars, albeit revised.
