- 1992 (black wheels, no widow's peak)
- 1994 (orange wheels, widow's peak)
- 2004 (redesigned, non-removable treads, no eyebrows, black smokestack)
- The redesigned 2004 Terence was released in the United Kingdom in 2002.
- Similar to the 1998 Toad, Terence has an incorrect magnet polarity.
- Until 2004, Terence had train wheels with treads added. Due to the train wheels, the treads would easily fall off the wheels.
