Did you ever wonder where the bunny came from? Or, for that fact, baby chicks? Or eggs?
I often wondered that, so I looked it up, and it all made sense. Rabbits, chicks, and eggs all represent new life.
It is also appropriate that the date of Easter is close to the Spring Equinox. Again, we're talking about new life: rebirth, the world comes back to life.
It all goes together, doesn't it?
I really don't think chocolate bunnies tie in, but I think we all could use a chocolate bunny! Or maybe some Marshmallow Peeps!
