Uh-oh . . . . .
That's always a danger sign with tumbleweed . . .
What else was in your cocktail? The gin on its own could melt a giant redwood probably kill a small piece of vegetation, although it isn't dangerous to human life, obviously, hahahahaha .
Was there anything in there that could have diluted it? Rat-wee prosecco, for instance?
Or Mortificadan Real Ale, which is largely gas and chemicals, with the odd hop and bit of ratshit just so the MortificadoBrewer (where is she, anyway) doesn't contravene the Dragon's newly-drawn-up legislation.
Hang on! The Princess hasn't been peeing on those tumbleweeds, has she? They could have built up an immunity to just about ANYTHING if they've had to survive her toxic alkie piss over the years.
I know for a fact that her need to empty her bladder every five minutes has led to a race of super-nettle which is threatening to destroy the Chelsea Flower Show.
