Hi, in my research I found the following toys:
This is 'Flosszilla,' created in Toy Product Design seminar MIT and squirts toothpaste from its mouth and dispenses floss from its tail. For more info please see their website : http://web.mit.edu/newsoffice/2006/toydesign-0524.html.
This is my second choice. Meet Nuigurumi Binsu. http://www.kidrobot.com/index.html
Meet Leonardo. This project is a collaboration between MIT and the world famous Stan Winston Studio. It combines the studio's artistry and expertise in creating compelling animatronic characters with state of the art research in socially intelligent robots.

In addition to the designer toys here are two soft toy patterns.
The next two images are the information about the tail.
The last instruction and set of images are the instructions for the head, ears and face.
