For instance, when manager Tommy Brown revealed that he was actually a woman in disguise, the following episode had her leaving the country for ever and being replaced by her identical twin brother.

It was shown again on Channel 4 in January 1991, however this time it was split into four episodes and featured the voice of comedian Harry Enfield.
This then spawned "The Viz Billy the Fish Football Yearbook", which described itself as The Official Book of the cartoon of the Comic of the Channel 4 T.V.
The film begins with the narrator explaining that young Billy Thompson was determined to be a football player, despite being born half-man/half fish.
Tommy Brown, the manager of Fulchester United offers Billy a contract to join the team.
But nearby, Gus Parker, evil manager of Grimthorpe City is watching and tells his sidekick Wilf that Billy is too good.
Later that week at Fulchester Stadium, the team coach Syd Preston has some bad news for Tommy Brown.
He tells him Billy Thompson has been kidnapped and that Fulchester have little chance to play at the football match on Saturday.
Meanwhile, Wilf and Evil Gus Parker are with Billy Thompson who has been tied to a football goal post.
At that very moment, an arm reaches out of a window overlooking the grounds and points a shotgun at Billy's replica.
Because Billy has been kidnapped and assassinated, Terry Jackson, the unsettled reserve team keeper will take his place.
Tommy Brown is not happy - with one keeper exploding and the next one being arrested this is just the kind of start the team does not need, but Syd Preston says that with 45 minutes left, the game could still continue either way.
Meanwhile, in the changing room, Syd Preston discovers the team has fallen asleep and the game restarts in 2 minutes.
Tommy Brown says that Rex has had a disappointing effort, but suddenly high above the stadium, the ball turns, flies into the goalpost and GOAL!
He explains that his small fish like body is the obvious choice to fly Rex's jet-powered air craft football.
But once again, Syd discovers it is not the real Maxwell Baxter, but another cardboard replica with a hidden tape recorder.
The next evening, before the cup clash with Rossdale Rovers, Tommy Brown introduces the team to their new member - Shakin' Stevens!
while Syd Preston explains that Stevens could be just the person the team needs for tonight's match with the Rossdale Rovers.
He suddenly remembers that the clocks went back an hour the previous evening, and that he forgot to change his watch.
The next day as the plane heads over the North Sea, Tommy Brown discovers Syd Preston has been replaced with a life size dummy packed with explosions.
He says this is not the kind of behaviour they tolerate in Botslavia and sentences them both to 30 years in prison... At the Kadaza stadium, Billy is revealed to be the only Fulchester player in sight.
The chief gives the order to fire, and the soldiers pull the triggers on their guns... Billy hears Syd Preston calling his name and wonders where he is.
However, Spangles tells Tommy it's in the best interest in Fulchester United's football club and turns his attention to a Mister Smith (who is really Gus Parker).
As the game gets under way, Billy's fish like brilliance is need to keep the high flying Redhurst players at bay.
Eventually, with the club name now Fulchester Albion, Tommy tells Syd that if they win the one remaining game against Grimforth City, they will be the league champions.
He announces that on Saturday, Grimforth City will win the league trophy, and no fish, large breasted Indian or invisible striker is going to stop them...
But with the scores level, Grimforth still have the advantage, only needing a draw to remain ahead and win the league trophy.
The narrator announces that Grimforth City have won the match instead of Fulchester United, and they are champions of the league trophy....
