Gamba is a Sea Other not a mouse as stated in the description, he and his friends (som muse and some rats) help the mouse on a island against the white ferret called the curse ( Noroi) in Japanese. They fight and kill a cat on the road, Some are slaughtered by Noroi"s ferrets and they meet many interesting animals on the road. A lot of good drama and intrigue. A must see for all anime fans. This is where it all began, Before Japanese cartons was called Anime in 1975.
This last lines is from the exit song:"This is where the journey stops.
The adventure comes to an end.
But Gamba pointed his finger
to a small island.
The seagulls are singing
the song of the devil.
The rising sun shines over the mast
but the evening sun will bleach your skull and those of your friends."
