I hear that... I really need to find the funds and a good excuse to pick these two up, but both of those are hard to do after the awesome Mandarake Blobs, the Cyclopus from the beginning of the year and the Blobpus Rangeas!
I think the OG GEM ver was painted on solid black vinyl. Its the first ever painted blobpus that came out at almost the same time as the unpainted black proto if i remember correctly.
I'm referring to the GEM transform version that has a clear purple body as opposed to the solid black.
Also - there were green Blob/Doku DXes released as well (kind of reminded me of the 420 ones, but I don't have one of those myself so I might be a little bit off on the exact color scheme). The DXes are limited to 25 a pop, and 4 total versions (2 Blobs and 2 Dokus). I don't often wish I were a rich man, but times like this...
