It's Spongetastic!

This book rocks! Not only is there a breathing evil sponge but a potato with sharp razor teeth...you can't get better than that. The story was very interesting, scary, funny and even awkward. It kept me reading for hours....I wish my sister would find a sponge of her own and leave me alone!

A Grool? That's new!

I like R.L Stine books because he leaves us hanging from a cliff at the end. He always writes stories that have never been thought up before. The Grool could not be destroyed by force or violence but Kat thought about it and found a way to destroy it. It wasn't very new that monsters be destroyed by love and kindness but it can't all be new! He did a great job and this book is really worth buying!

Are you sure its just a sponge?

I don't think this is just any sponge. Actually, its an evil sponge that feeds on fear and angriness. So don't even think about give'n this evil little thing to your dog!

Youst can't put it down!!!!!

This book is an exciting thriller.After every chapter you will be intense.The problem is based on a littlle old sponge that is bad luck.Just wait to see what happens in the end.

its about A bad luck charme, called a Grool.

This thing that look like a sponge is getting down right anoying for Kat, and Daniel for exampel once they buried the Grool in there yard, the next morning everything at that part of the yard was dead and trust me that is not the worst thing that happened to know the parts that are worse than this you can read this book.
