- Other Time Warner characters does not appear in Uncle Grandpa's Cartoon Adventure are the cast of Looney Tunes and DC Comics superheroes due to Six Flags has the rights of those two WB franchises.
- While the characters of there shows are animated by their respective studios, both the CGI rocket use by Aunt Grandma shown in the pre-show, and ride along with the CGI sets are animated by Warner Bros. Animation.
- The building that's holding the attraction is call Soundstage 92 as a reference to 1992 which is the year Cartoon Network went on the air.
