Not necessarily. Watching a bunch of Alone, you'd be surprised at how few calories small animals have. Pomeranians don't exactly have a lot of meat on their bones.
After many years of Japanese I just found out from this post that there's a counter for small things like seeds/nuts/grapes (tsubu). I thought they used ko.
OP is basically just a shitpost anyway, but the language doesn't necessarily indicate the origin of the app. Nintendo is a Japanese company but we can still play their games in English.
