The doll and mouse are so cute. However, it sounds as if your office mates are quite mean to this woman. She should report these incidents as harrassment and advise her supervisor or the head shed of these shennigans. This sounds so cruel to me.
As a child my 3 older brothers tthought it was funny to put things on me, especially bugs, spiders, mice, frogs, anything that made me cringe and scream and cry. It was horrid! I learned to stop it by means they did not like, but stop it I did.
