A person who goes by the name of  firefox1234 is currently running a survey regarding potential production of plushie ptribbles, and would doubtless appreciate input from Trekkies like you!

The survey itself can be found here: http://www.furaffinity.net/journal/2460998/

Really, who wouldn't want their own tribble? You can cuddle them, you can plant a tri-cobalt deivce in one and blow up the Starfleet captain of your choice, you can even wear them on your head!
