Tamama

Tamama is private second class of the Keroro Platoon. He is the newest member in the planetary invasion troop, and also the youngest. His name stems from the Japanese word otamajakushi "tadpole". While his age is unknown, Etsuko Kozakura has stated that she voiced Tamama as someone who was 19 years old. He is a very faithful subordinate to Keroro. Tamama is possessed of a tendency to have mood swings that border on a split personality, just like 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 usually accompanied by the sound of a balloon popping. Tamama is also prone to fits of jealousy, usually towards anyone who gets near Keroro (especially Angol Mois, who 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 because of his love of sweets, as revealed with 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.
