The Agents in The Three Musketeers

From the characters in The Agents Series comes a crossover of epic proportions. Perry, Pinky, and Doofy (Doofenshmirtz) are just normal janitors in an old-timey France, but their dream is to be royal musketeers. They get their wish, but it's not so easy as they originally thought. This is rated T (just to be safe). There's blood, "cartoonish physical violence," and some romance.
