Mrs. Terry is Mad Terry's mother. Mother and son live together in Tackleford, and apparently their house is in a pocket universe of some sort in which forgotten characters live... but it's actually just the forgotten space between the supermarket, railway station and football stadium. Mrs. Terry claimed at one point that the exit to the normal world is in her pantry, but it's really a tunnel in the yard. Mrs. Terry chose to live there in order for this place to serve as kind of sanctuary for his son, who is sort of a social outcast.
Inhabitants of Mrs. Terry's street include:
- Number 1: Mrs. Terry and her son themselves
- Number 2: Hugo Rodriguez (Runs the corner bar at number 3.)
- Number 4: Tessa Davies
- Number 5: Rachel Dukakis-Monteforte (Who is presumed dead in the outside world.)
- Number 6: Bill Tweedy
- Number 7(?): Natalie Durand (who is also presumed dead in the outside world, and has been seen doing a variety of things in the afterlife, most notably having the job of a Grim Reaper. Interestingly, Natalie is the only one who refuses to play along with what Mrs. Terry wants, and lives in an unusually fancy, albeit rather eerie house.)
- Number 8: Erin Winters and Eustace Boyce
- Number 9(?): Fallon Young
Erin and Eustace ended up at Mrs. Terry's place upon returning from Hell to the normal world (and after a short stay with Santa Claus at the North Pole), and a short time later managed to escape. Back in the normal part of Tackleford, they met an aged Hugo in his old sandwich shop again, accompanied by Fallon as his employee. It remains thus a mystery if Hugo and Fallon somehow escaped too, or if the ones at Mrs. Terry's (and thus all the other captives there too) were in fact some kind of alternate versions of themselves.
