Rodney was confused about the meaning of that clanging noise, so he thought he would ask on of the bunnies. They would need a good motivation to answer correctly, so he would have to bribe them. Still slamming into the kitty hard, he asks "Hey bunnies, what does that clanging noise mean? Whoever answers the best gets me next. Also if you try to mess the other up, then you are disqualified and get no turn, ever." He turns his attention back to his kitty, and starts to plow her faster. Just in case whatever that sound meant would interrupt this special bonding time.
