GEKKOUGA
ゲッコウガ
Pokemon name meaning:
ゲコゲコ gekogeko – alternative frog sound
月光 gekkou – moonlight
甲賀流 kouga-ryuu – The school of Kouga: an ancient school of ninjutsu.
Notes
The relevance of moonlight here is the ninja’s tendency to operate at night and the fact that the Pokemon has now added the dark type to its water type.
Members of the Kouga school of shinobi (ninjutsu) were trained in disguise, escape, concealment, explosives, medicines and poison. They were experts in techniques of unarmed combat (taijutsu) and in the use of various weapons.
The last officially known Soke of Kouga-ryuu was 14th headmaster Fujita Seiko (1898-1966). He taught prior to World War II, and earned such a reputation that he was inducted into teaching for the government during the war. He continued to teach privately after the war, and had many students who are still alive today.
Gekogeko is less familiar than the well-known kerokero as a frog-sound. Could there also be a side-reference to the similarly splay-fingered, huge-eyed gecko?

It’s based from the tree frog and bubble was a idea which I thought complemented this aqua blue tree frog
そうなんですか。きよしさんはあのポケモンの親さんですか？すごい！栄誉です。
えっ¬u < ？潔ーし
やっだ思いつき？ポケモン？光栄に思います、あなたの存在のために、
このようにそれを意味したのですか？
ちょっと誤解があったと思います。きよしさんの最初のメッセージから、きよしさんはゲッコウガのデザイナーなのだと思い込んでしまいました。それは大変栄誉だと思っていました。ドリーの頭が弱いですね(*ﾟｰﾟ)ゞただの人形てすから。
