The Arrival. The rayGun Rascals of Goosebump Galaxy

Once upon a time, the planet Mars was very different to what it is now. It was covered in red and yellow trees growing tiny slices of pizza, space houses made from cheese, and rivers flowing with tomato sauce. This was home to the RayGun Rascals from Goosebumps Galaxy. They lay claim to the universe, they mastered light speed travel, they invented the pizza. Ladies and gentlemen, boys and girls, let me introduce the pizza-loving, ray gun firing, masters of intergalactic mischief, The RayGun Rascals of Goosebumps galaxy.  In this book, the Rascals have had to flee their galaxy after turning their sun into a pizza and eating it.
oh yes, they also had war delacared upon them by some other alien folks.  This book is Crazzzzzzzy, fuuuuuunnnnnny and awwwwwsome. Wise words from children who have dared to be part of this madcap book world.
