Alone in His Teacher's House

...when Mrs. North asks him to dog-sit for a week. He gets $3 a day, plus a $4 bonus if nothing goes wrong. And he gets to be alone in Mrs. North's house! But pretty soon it starts to look as if Marvin won't be getting his bonus. Maybe he's not so lucky after all...

Marvin is pleased when his teacher asks him to take care of her dog while she's away, but he soon finds that there's more pressure involved than he likes.
