I watched a little tube mouse here once, running up and down the platform, dodging in and out of wall crevices whenever a passenger got to close for comfort. It reminded me of Mr Jingles, the performing mouse in The Green Mile.
 
Then the other night I noticed how greeny/ yellow the light actually is when you darken the contrast a bit. And the reflected harsh light gives it a even more of a 'Mile' feel, like when one of the inmates is 'ridin' the lightnin'.
 
And I like to think the West London cousin of 'Mr Jingles' still lives here.
