Sometimes when i check mai tamago's stats its happy and hungry hearts will be completely empty! And i'm like what the heck why didnt it beep??? D: I keep getting care misses
Does your Tama Go have an exclamation mark above his head? Because what I heard, your Tama Go only beeps after one more heart that the others empties (I'm not good at explaining)
For example:
If it takes 1 hour for one heart to empty, and their are 5 hearts, it will take 6 hours for your Tama Go to beep for attention.
But there are basically 2 hidden hearts on a Tama Go, which makes 7 hearts in all, so it would take 8 hours for it to beep.
The Tama Go is quieter than other Tamas, so even if it does beep it is harder to hear. I noticed this when I got my first Tama Go and thought it was broken.
