Well, the relevant lines in the Molecatcher are:

For cropping my fields and for ploughing my ground
This night will cost you no less than ten pounds

I would propose the following update:

For taking a ramble on my right of way
This night will cost you no less than 10K
If 10K is all then I do not mind
A pony a ride seems perfectly fine
