Psyduck (a.k.a. "Koduck" in Japanese) gets the Nanoblock treatment in the Nanoblock Pokemon series! This building toy is constructed by assembling tiny Nanoblock pieces (smallest block size is only 4 x 4 x 5 millimeters!). Includes 130 pieces and step-by-step building instructions. Exact measurements are not given, but these are typically between 1.75 - 2 inches tall when assembled.
Please note that this is a building toy that requires assembly; Nanoblock pieces are VERY small and tweezers can be helpful (although not required). They are NOT compatible with other popular building toy brands (such as Lego).
