Cold Comfort

Although originally aired in October 1997, this episode follows the events of the direct-to-video animated film Batman & Mr. Freeze: SubZero (1998), whose release was delayed after the poor reception of the live-action Batman & Robin (1997). "SubZero", a continuation of the previous Batman: The Animated Series (1992), was originally set for release in July 1997, which would have predated the fall debut of the revamped and redesigned series, "The New Batman Adventures".

The episode begins with the unveiling of a fully-restored Ultrasaurus skeleton. Not only has a complete Ultrasaurus skeleton never been discovered, it was shown in 1996 (a year before this series began) that Ultrasaurus was not a valid genus of dinosaur, the bones originally named "Ultrasaurus" actually being from two previously-known genera.

In the actual credits, Tress MacNeille was listed only as "Dr. Margaret Madsen," which left viewers confused as to who "Ice Maiden #1" was, since the last two credits were for maidens 2 and 3.
