The Red Queen and the Red King details

‘Here are the Red King and the Red Queen,’ Alice said (in a whisper, for fear of frightening them), ‘and there are the White King and the White Queen sitting on the edge of the shovel – and here are two castles walking arm in arm – I don’t think they can hear me,’ she went on, as she put her head closer down, ‘and I’m nearly sure they can’t see me. I feel somehow as if I were invisible – ’

Here something began squeaking on the table behind Alice, and made her turn her head just in time to see one of the White Pawns roll over and begin kicking: she watched it with great curiosity to see what would happen next.
