- The puppet that played the Lieutenant Burroughs also appeared as the Director of Photography in Martian Invasion, as an Helijet Pilot in both City Of Fire and The Impostors, and as Asher in Sun Probe. In Vault Of Death, it played Executive Carter. In The Perils of Penelope, it made a cameo appearance as a waiter on board the Anderbad Express. Two pictures of the puppet can be seen hanging on the wall in Maxie's office, in the episode The Cham-Cham.
- Burroughs looked rather different in Season 2. It's not clear if his puppet was modified or replaced with a new one.
