OK, so the mouse was originally called so simply because it came with a wired tail that was connected to your computer. Well, that is fine and dandy, but with the advent of wireless technology, the ‘tail’ is no longer needed – so why the heck did Elecom of Japan roll out the Oppopet 3-button Wireless Mouse? Wait a minute here, this cute little mouse comes with a tail as well – although it is not as long as your regular mouse cable. The tail is detachable, where you plug it into your computer’s USB port for it to double up as a wireless receiver. Cool, huh? You can choose from different tail styles including a cat, fox, squirrel, dog, dolphin, chameleon, pig, and rabbit.
