Here's Cream the Rabbit and Cheese her Chao! Cream is made of really light-weight plastic, and feels hollow. This figure has not much to it. It is also small, so she is in proportion to the other figures. Nice.
As you can see, Creams' ears are one with her head. This is a moulding issue, and would be tough to skirt without a seriously complex mould. It looks fine anyway. Cream has the same problem as Amy, because she's in a skirt, her legs don't really do much other than pivot. Her likeness is good though, she doesn't seem ulgy or unproportional. Her paint is nice and solid as well. Cheese is also nice, although he doesn't have 'fades' for the yellow tips. You can turn Cheese's head, but that's it. Cream is 3.5 inches tall, and Cheese is 2.5. (Or about 9 and 6 cm)
By now you may have noticed a rather distinct line around the bottom of the figures' heads. They ALL have this. It's another mould issue, where the head is made in 2 parts and fused there, leaving the line. Why is it ultra-visible on these guys? Who knows, because their other lines have it too...but it's SO far down toward the "neck" that you don't notice it unless you turn them upside-down.
So this line is actually a retro-problem. They solved it for most of their figures, and then failed to solve it on these later guys. It's very mysterious to see...but it's not so disruptive that you don't want the figures. Just odd.
