Tamama

タママ

Tamama is a private second class in the Keroro Platoon. He is the newest member of the planetary invasion troop, as well as the youngest. His name derives from the Japanese word otamajakushi, meaning "tadpole". Although his age is unknown, Etsuko Kozakura has stated that she voiced Tamama as a 19-year-old. He is a very loyal subordinate to Keroro.
Tamama has a tendency toward mood swings that border on a split personality, similar to his partner Momoka Nishizawa. While usually gentle and cheerful, Tamama can become a vengeful, raving maniac at the drop of a hat[1]. This change is typically accompanied by the sound of a balloon popping.
Tamama is also prone to fits of jealousy, usually directed at anyone who gets near Keroro (especially Angol Mois, whom he frequently refers to as "that woman").
Tamama likes junk food (especially candy, cake, cola, and potato chips) and physical training (he has his own private training room in the Nishizawa Mansion). In the anime, Tamama is diagnosed with high blood sugar due to his love of sweets, as revealed during a physical checkup.
Tamama's least favorite sound is nails on a chalkboard. He also dislikes Angol Mois and often calls her "that woman", as he considers her a rival for Keroro's attention. Despite this, Mois seems blissfully unaware of Tamama's hatred towards her.
