I got Jodi a tribble from Think Geek for Christmas this year (@CyberLizard got @JSWadley one too!), and it appears Ginger’s jealous of the new family member. She went on a Great Tribble Hunt tonight. They still sing songs of it.
Unfortunately we had to use my Blackberry to take this video, but it’s cute nonetheless. If you turn the volume all the way up, you might have a chance at hearing the tribble doing its vibrating and trilling whenever she pokes or shakes it.
