The first Kids' WB! Batgirl Bat-Trap Escape
Batgirl spots part of an ostrich egg shell, left from Penguin's demonstration of her fate.
As you can see from this vid-grab, Batgirl is tied down on a giant wooden fish!
To get free, Batgirl employs a means quite similar used by this site's Batgirl in the story Batgirl Cleans Up the Dregs.
Batgirl facilitates her own escapes, although she is swept out of harm's way just in the nick of time by The Batman.
