The comic book tale "Tales from Wild Space: A Tauntaun Tail" saw its release as the second story within Star Wars Adventures (2017) issue 22, hitting shelves on June 5, 2019.
Aboard the Star Herald, the droids BB-00, nicknamed "Boo," and CR-8R, known as "Crater," were embroiled in a dispute concerning his construction efforts. Emil Graf intervened, urging them to calm down, despite Boo's stream of insults directed at Crater. Graf sided with Crater, rebuking Boo for his impolite behavior. This talk of cooling down then triggered a memory of a story Graf once encountered.
Decades prior, Maxim, a sergeant serving within the army of the Alliance to Restore the Republic, was observing a tauntaun named Reebak for training purposes. When Reebak attempted to consume food, she was ostracized by the other tauntauns due to her unusually long tail. Seeking refuge, she sought sleep within a cave, only to be ambushed by a wampa that pursued her until she plummeted off a cliff.
Later during that day, Maxim noticed an odd accumulation of snow at the cliff's base and proceeded to investigate. There, he found the tauntaun, unconscious and slowly dying. He promptly requested a Tauntaun transport for her rescue.
After a couple of weeks, Reebak had recuperated and formed a strong bond with Maxim. Reebak was now prepared to begin her training. Maxim began teaching her to be able to transport Alliance personnel.
However, the Galactic Empire then initiated an attack against Echo Base. Imperial Cold weather assault stormtroopers were unleashing fire upon the Rebel evacuation starships. But Reeback and Maxim intervened, eliminating the snowtroopers. The Rebel Alliance managed to escape as Darth Vader, with his red lightsaber activated.
Returning to the Star Herald, Crater inquired about Reebak's fate. Graf revealed that Reebak had successfully escaped and rose to become a rebel hero. Graf then approached Boo, imparting the lesson that our differences can sometimes be advantageous. Boo however still thought he was in the right.
