I saw these Lego minifigure knock-offs awhile back on one of my favorite YouTube channels, Pinotoygeek, and had to get some for myself! Dargo Block World and LEBQ are a couple names these can be found with when searching eBay, most always shipping from Asia at reasonable prices, sometimes free. Check out my video:
In addition to the clear plastic colored Hulks, I had an Avengers-styled Hulk shipped, who came with a hammer and wrench ...? I guess Bruce Banner is a scientist, but it seems like mismatched accessories, which is sometimes the case with these imported minifigures. This Hulk has a swiveled head, unlike the clear Hulks in which the head is affixed to part of the torso assemblage.
More Later- Make It FUN!
