Plastigoop, my favorite thing, the stuff that makes the magic happen. Plastigoop first made it's debut in 1962 with the Vac-U-Maker. These early bottles of goop have the distinctive beetle on the front and are quite rare in used or unused condition.
Once the Thingmaker - Creepy Crawlers, had taken their own
direction independent of the Vac-u-form The bottles changed to the
black tear drop labels. These seem to be the most common type of
bottle as they were available during the production of most of the
original Thingmaker sets. There were a few variations such as the
red instead of black coloring for the the nite-glow and the
fleshtone goop. Icky Yuk was a different kind of goop that was only
issued with the Eeeeks! set. it was a bit more tacky and stretchy.
Icky Yuk had the tear drop style label but the secondary colors were
green as seen in the in the picture here of a mint Eeeeks! Set.
Green, blue, and yellow are the only colors of Icky Yuk that I have
ever seen. According to John Kolsar of
creepyfun.com not all sets of Eeeeks! included Icky Yuk. Another
interesting note about the Eeeeks! set pictured here is that Mattel
is already making the transition to their new labels, I call these
labels plain because... that is what they are.
Then came the Toymax years and the goop was flowing like it never
had before. Starting in 1992 Toymax began with hyphenating the name
to Plasti-Goop. They also picked up catchy side names like Magic
Maker and Fantastic Plastic. The goop came in the regular colors but
now there was also Glitter Goop, Metallic Goop, 4 colors of Glow
Goop. There was Color Change Plasti-Goop that would change color
with temperature. There was Stretch Goop, Eraser Goop and Plasti-Steel.
The Dolly Maker sets even had goop that was scented.
