Here is what we know: Eeyore’s Birthday Party organizers want you to bring drums, instruments and noisemakers, costumed self, costumed children, costumed pets, poi, juggling pins & balls, hula hoops, sidewalk chalk, stilts, facepaint and bodypaint.

Everything else is a guess. But the event this Saturday afternoon in Cal Anderson Park looks like a good way to extend your earth loving vibe into the weekend. There will also probably be a few hippie kids around you can borrow to score a free ice cream cone across the street at Molly Moon’s grand opening.

To put a little more Eeyore in it, there’s a 20% chance of rain in the forecast. No matter. After all, what are birthdays? Here today and gone tomorrow.
