Off the Rails

Off the Rails:

My name is Percy, Mark wanted to give me a little bath,

I ended up in the garbage disposal, feeling its wrath.

Broken, mangled and torn am I,

Don't tell Mark it will make him cry.

Percy will be going to the Thomas Hospital for repair. Mark has decided that giving his trains "a wash down" is not a good idea, at least in the sink where the garbage disposal is located.
