Slug? Cucumber?

[Fballer4310]

Anyone know what this is? I bought a feather duster and this guy was apparently stuck with it. Any ideas.. I'm afraid cuz I know some of these slugs or cucumber things could be poisonous.

Thanks Ben.. I saw that on live aquaria also.. That one has that excess "skin" running down the "back" though. The one I have is completely flat though so I don't know if it could be something else.
