Tamama  

, タママ

Tamama is the private second class of the Keroro Platoon, which is part of an extraterrestrial invasion force. He is the newest and youngest member of the team. His name comes from the Japanese word "otamajakushi," meaning "tadpole." Although his age isn't specified, Etsuko Kozakura stated that she voiced him as a 19-year-old. Tamama is loyal to Keroro and follows orders faithfully. Tamama has mood swings that can sometimes resemble a split personality. He tends to be gentle and cheerful but can also become vengeful and manic at the slightest provocation, often accompanied by the sound of a balloon popping. This change is usually triggered by jealousy, especially towards anyone who gets close to Keroro, including Angol Mois, whom he frequently refers to as "that woman." Tamama enjoys junk food like candy, cake, cola, and potato chips, and also likes physical training. He has his own private gym in the Nishizawa Mansion. During a physical checkup, it was revealed that Tamama has high blood sugar due to his love for sweets. His least favorite sound is nails on a chalkboard, and he dislikes Angol Mois, often referring to her as "that woman." Despite this, she seems unaware of his hatred towards her.
