You've already mentioned this in previous posting, Carpe, but hey if the bashers are flogging a horse... ;)
It's also easier for SPNG to follow up Spongebob product with other ones as well -- you go to a buyer that's already selling Spongebob products and say "Hey how's Spongebob line doing? Well? Great. we have these other products lines too", guess what, if the Spongebob line is doing well, most likely they'd be willing to check out other one lines too.
