The sizing of this costume was fairly accurate but it very cheaply made. After only a few wears, the mask and belt both broke. I wouldn't recommend this costume.

The bed needs air refilling more often than I thought it would- every 3 days at the most. So much so that if I didn't pump it, the bed would all be like a water bed with "jelly-like" feeling. To lessen this effect I situated it in a corner of the room against the walls. Further more, what surprised me was the round water condensation on the bed sheet just underneath my (head) pillow in the morning. But what confuses me is that in the evening the bed feels cold (or the air inside feels cold).What I like about it though is that the pump works real fast in inflating- although it is loud for an evening activity.

Ex Output:
Negative

I did not like this book because it was not like a complete story. It just had little mini stories in it. I also did not like it because some of the authors who wrote the stories did not finish them. One more reason is there are a lot of pages, but it is not hard so it makes it too easy to read.The book Scary Stories is a book filled with about 10 different stories. It is very scary andit just makes you want to scream! This book will scare its reader half to death.The type of reader that would like this book is maybe someone who watches a lot of horror movies. The reason is because it really scares you. The reader would also have a strong stomach because it is a gross book.

Ex Output:

Negative
