Hey Arnold!: The List / The Haunted Train

S1 E1: Arnold's best laid plans for the "Ultimate Saturday" go up in smoke when he tries to complete all of his favorite things to do in one afternoon. All the while, Grandma and a team of wacky movers try desperately to move a piano into the building. On a boring summer night Grandpa tries to liven things up by telling a story about haunted Train Number 25 which comes back to earth on the anniversary of its last ride -- the mad engineer wants to take unsuspecting passengers away to the spirit world!
