Sadly, squirrels never pop up around here. Possibly because I live on a squirrel-free landmass.
I am making a tarot deck at the moment and am tempted to make a Happy Squirrel card of my own. Except that mine is based on the New Zealand environment, so it won't be a squirrel!
But one thing I would point out, and it may have been mentioned already, the Happy Squirrel may be the 23rd card in the major arcana, but wouldn't his number be #22? Because the Fool is #0.
And thinking that, I might make a #23 = Chaos. Maybe that can be the earthquake card.
I made one original Happy Squirrel for the Tarot Noir...but only one person was lucky enough to get him!
(there is also a single original Minute deck Happy Squirrel...that I sold with my working deck on ebay...alas I never scanned it.)
To me they are a novelty and I don't use them in readings. Like the title cards, and other 'extra' cards, I just keep them in the box.
