The Big Black Bat is used by The Registrar as a kind of executive transport, flying it around Infinity in style.

The BBB is a strong and fast flyer, if a bit miserable. However, back on earth the creature’s unreliable echo location was its downfall. Like the first versions of many new inventions, it simply didn’t work!

Suffering from an appalling sense of direction, Big Black Bats would set off every night to explore and forage for food only to fly straight into the walls of their caves.
