Well, they are judo dogs. That is, judo is their passion. Roy and Rexley live in the same flat, and they both have black belts in judo. Roly is Roy's cousin, recently come to visit, and he's a rank beginner...only a white belt. He wants Rexley to do some judo with him, but Rexley despises Roly and he can't be bothered. Roly does the Hip Hop and Rap style chatter all the time, and Rexley can't stand it. That pretty well covers it, I think.
