More astrology stuff.....pass up if not interested.
Found it in my Linda Goodman's book....surprised, I thought it is one of the more esoteric ones~
It's grey lizard not squirrel

here's her take on it. BTW, not proofing so bear with any type-os.
A few Pluto people fall somewhere between the eagle and the stinging scropion, vicitms of their own black magic. These are the grey lizards. With them, supreme self sacrifice becomes neurotic concern about the self, and psychic abilities cecome fearful apprehensions of the lurking evils which may strike at any moment. Foreceful courage twists itself around, and instead of seekng the ruthless revenge of the stinger scorpions--or rising above such bitterness like the eagles--they bitterly withdraw in tangled hatreds at each minor injury, hoping fate will punish their enemies, almost uncousciously willing destruction without direct action.
They gray lizards fail to draw on the power of Pluto in their natures--power that could lift them high above all the unfortunate circumstances that surround them. In the very teeth of tragedy, this awsome inner strength could give them new life in the sunlight. But they seek the dark shadows and lie dormant, a pathetic waste of the brilliant potential of their birthright. Still, Scorpio can never slide deep enough into the slime of bitter depression to completely lose the power of Pluto. it's never too late for the grey lizard to transfrom himself into an eagle. That kind of deep magic belongs exclusively to every person born under the Sun sign of Scorpio. All they need do is to call on it.
The other books mention the Eagle/Scorpion dichotomy, but this was the only place I remember reading about the grey lizard....or the gray lizard for that matter!
