Very nice story; however, I've seen some grammar errors. You're missing periods, question marks, commas, and exclamation marks at the end of the character's sentences

For example:

''I don't know'' said Rita. ''Stay here and don't come out''said Roddy hiding her in a cupboard since both him and Rita sensed the danger.

It should be like this:

"I don't know," said Rita. "Stay here and don't come out." said Roddy, hiding her in a cupboard since both him and Rita sensed the danger.

I hope I am not being rude, I was just being helpful, that's all. I hope you keep that in mind next time you decide to write a fanfic,

Wow cool! Thanks! I would like that! I'm planning on making the Great Coyote Detective with Wile E. Coyote as Basil. Good Luck!
