Ugobe, Inc. has released a new version of software for Pleo, their baby robot dinosaur. This update adds several new behaviors including singing, the ability to sit on his hind legs, a new high stepping gait to accommodate difficult carpets, and better recognition and interaction with his training leaf. The update also includes the ability for Pleo to develop personality quirks such as getting a cold, foot stomping and itching, and other spurious behaviors. The update is free to Pleo owners and can be downloaded from the 1.1 update page.
