Brian's Krusher plug got me thinking about another plugged toy, the elusive Ooze-It, which I've discussed with Arto before a few years back.
Rather than air, Ooze-It was filled with red goop, which would ooze out of various head orifices, if unplugged, when the green figure was firmly squeezed!
The green guy is clearly part of the slime craze, which continues to this day.
There's a description of the uber-rare Ooze-It on Stretch Armstrong World as he's classed as a distant cousin of the Stretch family.
Sadly Krusher isn't in the index. Too much hot air I expect. You need syrup or slime to get in.
Are you lucky enough to have an Ooze-It readers?
