Creatures of Japan 1: Kero Kero ケロケロ! Frog! (possibly the Kajika Frog / カジカガエル)
This is Pajero, he goes kero kero....
....he likes to climb the walls, 'cause he's a plucky fellow....
....and as he gazes to the horizon, he accomplishes his mellow.
This is possibly a male Kajika Frog (Buergeria buergeri), 河鹿蛙（カジカガエル）. The kanji for Kajika mean
river/stream (河) + beast or hunting (鹿)-->river hunting frog, river beast
frog? Second kanji also means deer, but I don't think it applies here. If you know better, give me a shout.
