I was so zealous in Series 2

I didn't notice the potions were all nameless brews

Not that inventive, we saw it twice

Without a name, potion bottles are a dull device

Yet we saw even more

In Series 3 and 4

And 6 and 5

Oh man alive

It's such a bore

Do go naming every potion

Way down to Level 3

In Series 5 came some surety

We saw a potion which had a name: Impurity

And now the labels could make us think

Though did we need one that had 'I am' and added 'DRINK'?

A thirsty dungeoneer

Who's far too young for beer

Can ditch the Sprite

And down True Sight

To make things clear

Do go naming every potion

Way down to Level Three

Don't go titling creams and lotions

Drinks it has got to be

But naming was open to misuse

Just who came up with the bright idea of Goblin Juice?

And do we know how Fast Backwards worked?

It rewound time itself, sort of, with logic shirked

Now mix calligraphy

With creativity

And give each phial

A touch of style

For us to see

Do go naming every potion

Way down to Level Three

Don't go titling creams and lotions

Drinks it has got to be...
