As a kid, I had the entire collection of Star Wars action figures (and still do), but I think my favorite action figure toys were actually Micronauts. These things were so cool - you could take them apart and snap pieces from different figures together. And they had a super-cool pneumatic tube transportation thing. Totally cool stuff.
It looks like after 25 years, the Micronauts are returning!
