I recall a friend nicknaming a Series 2 wall monster "Arseface of Legend" - so here is a parody from the point of view of a Watcher tuning into Series 3 to discover clue room guardians who look somewhat different. Original is Brown Girl in the Ring, made famous by Boney M.

Brangwen in the wall

Tra la la la la

There's a Brangwen in the wall

Tra la la la la la

Brangwen in the wall

Tra la la la la

She looks like a face and not a bum

Bum bum

Wait in her clue room

Tra la la la la

Careful she could bring you doom

Tra la la la la la

Is she a hoodlum?

Tra la la la la

She looks like a face and not a bum

Bum bum

Olgarth Granitas gone off

Need a face that works with blues

Arsehead Igneous gone off

Need someone to give the clues

I remember on one Friday, right

She was being a hard-faced cow

'Cause a team were slow with her riddle

She said, "Answer" and "Name it now!"

Brangwen Shee

Now you see

Brangwen in the room

Tra la la la la

There's a Brangwen in the room

Tra la la la la la

Brangwen in the room

Tra la la la la

She looks like a face and not a bum

Bum bum...

This one is based on the full theme song from TV series Gladiators.

Do you fear the power of the Automatum?

Can you meet the challenge of the catacombs?

Do you have the makings of a hero?

Can you run pell-mell for the well?

Do you have the speed, the strength, the ears to hear his whirring

Setting your heart stirring?

Or is it your bowel?

Beware the Automatum

Gotta move like a hare on steroids

Gotta stay ahead of the android

Gotta seek your Holy Grail

Ready or not, here he comes with a flail

Can you keep away from the Automatum?

Do you have three friends to aid you?

Do you have the smell of perspirin'?

Can you keep on moving to your goal?

Now it's time to race, you're in a chase, so don't you crack now

There's no turning back now

Edmund's on the way

I mean the Automatum

Gotta move with lightning speed

Nearby portal's what you need

Better collect the MEDAL bits

Oh he stopped you, time to call it quits

Do you fear the power of the Automatum?

Can you face the menace of the mechanoid?

Show the stuff you're made of

Karen, seal the fate of

The Automatum

Spellcast RUST at the Automatum

Then you'll bust up the Automatum

But you won't be a champion

The Automatum!
