I had to Google that. Basically small model puppets a few inches high with a disproportionally big head, yes?
Any decent macro lens in the 90-200mm range will do. Which makes for easy picking since it's pretty difficult to find a really bad one. Micro Nikkor, Tamron, Sigma etc.; take your pic(k).
Distortion in the sense of barrel/pincushion won't be much of an issue with virtually all dedicated macro lenses.
Heck, you could even get away with a long-ish standard lens and an appropriate extension tube.
You got the lighting covered?
