List of Sgt. Frog episodes

The episodes of the Sgt. Frog anime series, also known as Sergeant Keroro and originally titled as Keroro Gunso, is a Japanese television series produced and animated by Sunrise Inc. It first began airing in Japan on the television network TV Tokyo on April 3, 2004, and has since broadcast over 300 episodes, which are normally constituted from two 15 minutes shorts mostly and sometimes one 30 minutes story. The anime is an adaptation of Mine Yoshizaki's manga series of the same name, which was first serialized in Japan's Shōnen Ace in 1999, and has been toned down for children instead of focusing on teenagers. The anime itself is divided by seasons with a duration of a year (51 episodes per season, one per week except for the first week of January), always starting and ending the first week of April.

The five main frog-like aliens. From left to right: Tamama, Dororo, Kururu, Giroro and Keroro.

The series centers around the attempted invasion of Earth by a Platoon of 5 frog-like aliens and the mishaps that their incompetent and lazy leader cause. Around them are the human figures that help them understand earth's culture.

The first English dub of the show to be released was titled Sergeant Keroro and aired on the Southeast Asian TV channel Animax Asia. It premiered in 2008.[1][2]

In 2009, Funimation Entertainment released the second English dubbed version of the anime. Funimation's dub was released in North America, and has spanned a total of six 12 to 14-episode DVD sets, with the first four sets later released in two larger 25 to 26-episode box sets. To date, the first 78 episodes have been released in English by FUNimation.

The title for each episode of the series always starts with the name of a character that becomes the episode's focus.

Sergeant Keroro is a frog-like alien from the planet Keron sent to invade planet Earth (or Pekopon, as his race calls it). He is instead kept as a pet and forced to do chores for the Hinata family, which consists of paranormal maniac Fuyuki, his ill-tempered older sister Natsumi, and their manga-editing mother Aki. Keroro is given his own room in the basement of the Hinata family house, which he refurnishes and uses as a base, not realizing that the room is haunted by a ghost.

In a prequel to the first segment, the Hinata family first discovers and captures Sgt. Keroro while he is scouting inside their house. Fuyuki takes the Keroball (Keroro's weapon) and fiddles around with it, accidentally sending a signal to the Keronian invasion fleet alerting them of Keroro's capture. The fleet abandons Keroro instead of rescuing him, leaving him to perform chores around the Hinata family household.

Momoka angrily attacks Tamama, but Keroro arrives and saves her before the seemingly helpless Tamama snaps and counterattacks with his laser breath.

Momoka attends a meeting for Fuyuki's paranormal club at his house in an attempt to become closer to him, but is frequently interrupted by Keroro and Tamama's antics.

Keroro eventually discovers that the badge on his helmet allows him to temporarily turn invisible.

Natsumi suspects that Keroro will use his invisibility device to go out and cause trouble, so she convinces her family to install hidden cameras throughout the house to spy on him. Later, Natsumi accuses Keroro of spying on the family when she discovers a pair of binoculars outside, but the Hinatas survey the security footage to find that Keroro has done nothing out of the ordinary.

Giroro suspects that the reason behind Keroro's lost interest in the Pekoponian invasion comes from a difference in humidity between Earth and Keron. He and Tamama install humidifiers in Keroro's room, which drastically increases his intelligence and strength, but the room becomes overly humid when it begins to rain, causing Keroro to go berserk. The humidity attracts a Nyororo, a natural enemy of the Keronians, which feeds on all the moisture Keroro had absorbed and returns him to normal.

Starting season 6 Keroro is now full HD and having headroom.

Season 7: 2010 - 2011

The seventh season of the Sgt. Frog anime series had its running time reduced to 15 minutes in its original timeslot. However, a 2nd timeslot, which reruns the first 15-minute story and presents a new 15 minute one, called Keroro Gunso Otsu (ケロロ軍曹乙), was created. The "A" stories are the ones shown in the old timeslot, while the "B" stories are exclusive to the Otsu timeslot.

After timeslot changes caused by the 2011 Tōhoku earthquake and tsunami, episode 356 was announced to be the final Keroro Gunso Otsu episode, with two stories exclusively airing in the night timeslot[3] at a timeslot of 3:05 am, the announcement also referenced in the first airing of episode 355. However, after a few days that announcement was changed, and Keroro Otsu was just delayed for one week, returning to the original plans for the series' ending,[4] although airing everything one week later.

The last episode coincidentally aired on 3 April 2011, exactly seven years after the series premiered on 3 April 2004.
