This is the first time Kaa has appeared in animation ever since The Jungle Book 2 (2003) released 19 years prior. And this is the second time he is voiced by a female actor after The Jungle Book (2016) and this is also the second time since 2003 where he is voiced by someone other then Jim Cummings.
None of the original Disney actors returned to do their roles in this short as the Disney villains even Pat Carroll who died 2 months ago before this short debuted.
