Dinosaurs aren't the only supposed extinct creatures causing havoc in post human Tokyo. Check out what some players found in Tokyo Jungle:
Yes, it's AIBO, Sony's robot pet dog. You may recall that Sony took Aibo out back and shot it a few years ago.
Somehow, AIBO outlived man. And not just the good kind of AIBO. In Tokyo Jungle, AIBO will have to fight... AIBO!
There's actually just a bit more to AIBO's appearance in Tokyo Jungle than a simple cameo. This is probably spoiler territory, so I'll leave the details to this Japanese blog which provided the pics.
