In The Robot Chicken Walking Dead Special: Look Who’s Walking, which premieres on Adult Swim on Ocober. 8, Glenn does indeed find Maggie, in a skit called “Happy Glenndings.” And without spoiling the particulars of the comedy, we’ll just say that Glenn’s final words are oft-repeated, and they also form the narrative for his post-Negan attack life with Maggie in the sitcom-within-the Robot Chicken special.
Old Man Carl, as well as younger Carl, is voiced by TWD star Chandler Riggs, who’s joined in the special by co-stars present and past, including Andrew Lincoln, Norman Reedus, Jeffrey Dean Morgan, Sarah Wayne Callies, Jon Bernthal, Lennie James, Steven Yeun, Scott Wilson, Danai Gurira, Melissa McBride, Michael Rooker, and Josh McDermitt.
Both Green and Senreich say Lincoln may have enjoyed recording his lines for the special the most, as he fully embraced everything, from Rick’s scenes with a frisky unicorn to Rick’s attempt to come up with a new name for his group of friends and family.
Dan also guest stars in singing the Terminus song you can hear his voice in the chorus.
