WowWee has expanded its range of Alive robot animals beyond Elvis and a chimpanzee to include a lion, panda, polar bear and white tiger cubs.

The new friendly-looking robots feature realistic fur, an animated face, and recorded sounds activated by touch and tilt sensors.

Offering fully interactive features, WowWee say that the robots will even have lifelike responses. Picking the lion cub up for example by the scruff of the neck and his legs will go limp, like a real cub being carried by its mother, or leave him alone for 5 minutes and he will purr himself into sleep mode.

Pocket-lint got a hands-on with the new range and can testify to their cuteness. What's impressive too is that unlike other robot toys, the battery pack is not easily felt through the toy's fur, giving them real soft-toy appeal.

The new "Live Cubs" will cost $59.95 when they are available in the States in September and run cheaply off four AA batteries.

A WowWee representative revealed to Pocket-lint that a Koala cub version may be forthcoming, but has not been officially confirmed at this stage.
