M&M's and Nerds aren't exactly antrhopomorphic...But I can see Nerds as familiars (for some odd reason...).

Other candy ideas:

"Turtles" (carmel blob covered in chocolate, with pecans sticking out to mimic legs and a head)
Gum drops and spice drops
Fireballs (and Atomic Fireballs - C'Mon, it's just asking to be used!)
Pixie Stix
Good N' Plenty (sounds like high-quality rations to me!)
Wax Lips (...da** I hate wax...I must insist that these be monsters of some kind)

And I'll seccond the "licorice whips" idea...in fact, sometimes they are labeled as such.

I'll think more later.
