Space Dog Jack and the Haunted Spaceship — Susan Schade

In this Level 1 Hello Reader!, Space Dog Jack goes on another adventure with his old pal Earth Dog Bob and saves Earth from a haunted Halloween spaceship.

It's Space Dog Jack to the rescue when his friend Earth Dog Bob sends him an urgent message:
To: Space Dog Jack
From: Earth Dog Bob
WE ARE IN DANGER
FROM A BLOB!

But Jack and Bob soon realize there is no blob at all--it's just a trick! From their spaceship, they board the mysterious ship that's trying to scare them. When ghosts and goblins give them a scare, Jack and Bob use a mask to chase the ghosts away. Now heroes on Earth, Jack and Bob go trick-or-treating.
