Alice’s Story
“It happens if you speak here in this mouse? I think maybe this mouse also speak. ”

Alice was talking to a mouse.
“Oh rats, Do you know the way out from this pond? Swimming here, I had been very tired.”
Mouse is looking at the Alice in eyes that was wary, but do not say nothing seemed to wink.

“Not a know the word? He came with William the Conqueror, it must in France rat!”
So Alice was talking again.
“Ou est ma chatte? (Where is my cat?)”
This was sentences written in the first French textbooks.

Rats were suddenly jumped from the water, and seemed out trembling rattled afraid.
“Oh I’m sorry! You had forgotten to cats hate”

“If I hate cats!” Murine cried in a high-pitched voice.
“If You’re is me, I wonder if cats will like?”

It is in the “rat”, but it is not in the “Alice”.
It is in the “cat”, but it is not in the “echidna”.
It is in the “monkey”, but it is not in the “Koala”.

What is there?
