Someone going by the name of Mechapone apparently ran into a plushie version of Grubber over on eBay. Unfortunately there don't seem to be anymore up anywhere, but considering how dominated eBay has become by Chinese factories pumping things out, it could either be a leak from the factory floor, or a knockoff.
Regardless, he exists. Hopefully we will see more soon.
Thanks to Raritymlp and Reltof for the heads up.
