Mallory: The best thing is the slippery steam train, you'll be more slippery than ever before!

slippery snakes 

Basically a wolf in sheep's clothing. Nobody ever notices the snake in the water until it's too late unless you are really looking for it or its too late. Slippery snakes are usually the sweetest kindest people who are usually doing too much. They do this to earn ur trust and sink their teeth into your life so that they can slyly manipulate you. It is difficult to identify this person until they ruin your life but nobody will ever believe you until it happens to them.

K is such a slippery snake. She found me somewhere to live and was nothing but nice to me, but then she suddenly went behind my back and put my job in jeopardy for no reason. You have got to be careful with slippery snakes.
