Gamanosuke (がまのすけ Gamanosuke) is a male Tamagotchi who appeared in the Tamagotchi! anime.
Gamanosuke's name comes from the Japanese word gama (蟇), which means toad. Nosuke (のすけ) is a rather common ending in Japanese names, such as Jounosuke or Shinnosuke.
Gamanosuke looks like a giant toad. He has dark green warty skin, a white belly, and a yellow beak. There is a red scarf tied around his neck.
Gamanosuke has a pleasant disposition. Despite his large size, he is actually very gentle. He has a strong tongue which he uses to grab and hold things.
He acts more like a Tama Pet than a regular Tamagotchi, since his behavior is more animal-like, and he can't speak normally. In the Japanese dub, he can only say the word gama. In the English dub, this was replaced with 'ribbit'.
In the Anime
Gamanosuke appears in the episode "Kikitchi's Ninja Training". He suddenly appears while Gozarutchi is sharing his lunch with Mametchi, Kuchipatchi, and Kikitchi, and this causes Kikitchi to panic and run away Gozarutchi explains to Mametchi and Kuchipatchi that Gamanosuke is his training partner, and that he's actually quite harmless. Kikitchi is scared on Gamanosuke for a while, and tries to run away from him. After Kikitchi falls from a great height, Gamanosuke catches him with his tongue and saves him from getting hurt. Then Kikitchi discovers that Gamanosuke is actually quite friendly, and he is no longer afraid of him.
