Trying to recall an old children's toy

[James]

They were these little figures. They were rubber balls with faces on them, and then you could fit the balls into little bodies and put a headpiece on some of them. There was a whole bunch of them, and there was even a playset where you could roll the heads around town and shit.

I think they were called Nerfels or something like that, but I can't find any information online for them.
