Fren-Z is really nice. The entire figure is a mix of stiff vinyl and hard plastic. There are 4 points of articulation: hinged jaw, and 3 hinges in the body (separations between organic and mechanical parts). The body hinges allow for some pretty realistic swimming poses. The hinged jaw is almost deep enough to "swallow" a 4" figure. Some additional hinges on the ventral fins would have been nice, but it is still great without them. The sculpting is great, although some of the mechanical details in the midsection are a little soft. The paint is alright, if simplistic. These are intended for kids after all.
