- Development Gag: Nearly any time you see a letter or a name on the clothes of a minifigure, it's most likely a reference to one of the designers at The LEGO Group.
- What Could Have Been: Mr. Good and Evil was originally going to be called "Dr. Splitz", but the name was likely unused because it would give the character a real name, while the other Minifigures' names are more like titles or nicknames (Fisherman, Circus Clown, Fortune Teller, etc.) Although the final name is technically very similar, it resembles a nickname more than a real name.
- The series 4 minifigure 'Hazmat Guy' was originally going to be featured in an earlier series, but the moulding was proven to be complex so he had to be delayed.
