Food
Use this icon when you want to feed your Tamagotchi.
There are two options: ごはん [Meal] y おやつ [Snack].
Meals fill their Hungry meter and increase their weight by a gram, and snacks will fill their Happy meter and increase their weight by two grams.
Take a look at the item list if you want to see all the food items you can get:
You will never run out of any food item, no matter how many times you use them.
Some Tamagotchis have a slightly different way of eating.
Senior characters eat slowly and the least healthy characters are a bit messy...
It seems there's a hidden snack that fills the Happy meter without increasing the weight...
It could be useful if you don't want to increase their weight too much.
