The QMx twitter account also recently posted a comic strip based on their Trekkies version of Star Trek, which also featured a tribble:
QMx aren't the only ones in the tribble business, Diamond Select Toys are also re-releasing their electronic purring (or screaming) and wriggling tribbles this summer. It will be interesting to see if the QMx versions offer anything different (make them climb walls? come with litter of baby tribbles inside??).
