I'm trying to find a specific giant Archie comic published in the Sixties.  It's probably an ARCHIE'S PALS 'N' GALS or maybe an Annual, but the Grand Comics Database doesn't list it, so let's see if anyone can find it.


1)  A story in which Archie transforms himself into Reggie with the help of a secret formula.  Jekyll / Hyde riff.


2)  A story in which Archie misinterprets Betty and Veronica having a verbal cutdown session as having a real fight, and the girls later get into a real fight.


3)  Moose hears about playing bridge and puts a board across two boxes, pretending he's crossing a bridge over a river.  (This one turns up in some reprints and it's only a page long.)


Any help?
