One of Timothy's favourite amusements was to stalk anyone who would play with him, and so, when I came to live with Grandfather, I became one of the tiger's favourites. With a crafty look in his glittering eyes, and his body crouching, he would creep closer and closer to me, suddenly making a dash for my feet, rolling over on his back and kicking with delight, and pretending to bite my ankles.
I don't know how `crouching body' look alike. Could anyone give me picture of the same? or explain how crouching body look alike.
Also, I think, creep = move slowly. Am I right?
Also, please explain phrase `rolling over on his back'.
