Here's a picture of the one from Pee-Wee's Big Adventure (camera picture of TV .. i.e. very bad quality).
Now that I look at it, I think ours was slightly different than this (e.g. more "hair", and it was solid color). At this point, I'm not even sure what the hell kind of creature that's supposed to be either.
Anyway, someone please reply if this rings a bell
thanks,
