A thought wave was a natural telepathic ability of the Wookiee species from planet Kashyyyk, allowing them to communicate mentally over greater distances. It required a Wookiee to close their eyes, picture the one they wanted to send the message to, and concentrate very hard. Some time after the destruction of the first Death Star, the female Wookiee Mallatobuck sent her husband Chewbacca a thought wave while he was orbiting around Kashyyyk, wishing to warn him their son Lumpawaroo was in danger. When he received the message, Chewbacca jumped up from his copilot seat in the Millennium Falcon and let out a gigantic roar, which frightened his captain and friend Han Solo.

Behind the sceneEdit

To date, the only canon appearance of the thought wave is in The Wookiee Storybook, a 40-page children's book published in 1979.
