Oh of course. These things look like they would topple over in an instant. Not to mention the plastic is probably not all that great.
So while reading some back issues of Ultimate Spider-Man, I found an ad for these:
A quick Google search showed very little on them, outside of some eBay listings. I'm not even sure what the name of the brand is. Is it X Blocks or Blocks X?
Oh I remember those, I only got one set with Spider-Man, Doctor Octopus and some gem.
Why does it tell you to discover the action features for yourself? That's a key part in Lego's advertising!
