This wonderful tradition started well before Galore.
At a show on TGOE's fabled "From Airheads to Tuneheads" tour, Greg mentioned that his Dog (fluffy's) favorite toy broke. At the next show, a couple brought toys and threw them on stage for Greg. Greg loved it so much he encouraged fans to bring soft, squeeky toys at each show.
The tradition gained a lot more relevance during the Galore years after Fluffy's passing. I know I don't need to rehash the heartbreaking yet moving concept of "Galore", but Greg was moved to tears at the kind words everyone had and the toys everyone brought for Pacific.
I encourage everyone to keep up the tradition. At Sandbagger's Amanda and I were sure to bring a couple of new toys for Pacific (who's a pup no longer, let me tell ya!) Greg was touched, as always. In intercity, you may be able to hear Greg using one of the toys as he's performing.
