Is Nagagutsu San the neko atsume version of puss in boots? Could very well be since Nagagutsu (literally long shoes) means boots. Nagagutsu San only comes for the mouse wand toy thingy.
Physical characteristic: small moustache
Treasure: a hat with feather – a small beautiful hat with a water bird feather
Here’s Nagagutsu San looking all dashing with his sword through the mouse toy!
