squeakers?

[a-starstar.livejournal.com]

Hi! I just recently found this community, and I was hoping someone here could help me out with a long-time problem of mine. I'm obsessed with those squeakers you find in dog toys.

They're self-contained little plastic bubbles with a metal/plastic squeaker device on one side. I want to buy them in bulk for sewing with instead of cannibalizing dog toys all the time -_-;; I can't find them anywhere, though. Any ideas? Help would be greatly appreciated. Thanks!
