Ok so Fangface isn't Hanna Barbera, it was produced by Ruby-Spears but the pet detective formula gave it the same feel as a Hanna Barbera cartoon so it was another favorite of mine from the late 70's.
Biff is another of those male designs that have unrealistically broad chests. Not ideal for the block figure design but I prefer the female characters be more accurate and they are so I'm happy.
A Custom A Day....
I began toy collecting as a hobby back in 1990 I have always had a
need for custom figures. Toy companies begin action figure lines, begin
to release individual characters to create teams and, more often than
not leave them incomplete. Many collectors find that custom figures
pollute their collection's authenticity by not being mass produced
creations from the toy companies that created the preexisting toy lines.
I disagree. I feel a quality custom action figure enhances a
collection and help create a complete picture.
