Blizzcon Badge - Crying Murloc No 0-3 Velcro Badge

Mint condition, never opened Blizzcon Badge! I'm not sure what this is supposed to be but it's a crying Murloc and it says 0-3, I assume it's b/c badges are not for kids and are for backpacks only. *SINGLE BADGE ONLY!* Bundle and make an offer to haggle on multiples.
