1. Tamas evolve a lot younger these versions. Don't worry, it's normal.
2. I've witnessed a V4 death. Here are the sequence of events.
- Tamagotchi lies face flat on ground with skull over head, and the buttons lock up and there's this weird, kinda scary beeping
- After a few minutes, the beeping stops and the Tamagotchi still flat on it's face rises up the screen.
- Black Passes across the screen up
- When the blackness stops, the angel thing clicks on the screen, and starts floating
I will never forget that.
And, right now I don't know of a way to stop this.
