Sgt. Frog Season 3 Episode 147 Paul: A Butler's Duty, Sir! / Giroro: Who Gave It to Me, Sir?

Momoka's butler, Paul, thinks it's time to retire, so he tries to find his replacement by hosting a tough audition competition that brings in both mysterious (the Masked Butler) and audacious (Keroro) participants. Later, Valentine's Day rolls around again and Giroro gets chocolates from Natsumi. Or at least he thinks he does... but to be sure, he has to investigate all the possibilities.
