I kind of want to have another go at making an in-character account, but after https://twitter.com/sherbetpony and https://twitter.com/novathesquirrel got mostly ignored I feel like that would repeat if I tried that somewhere with less visibility and discoverability.
On Twitter I was able to find a bunch of accounts to try and poke and I had what I thought was an interesting premise with Sherbet (though I may have been too subtle) but that didn't help too much.
I think the Pac-Man Tamagotchi actually lets you just keep a character indefinitely if you take perfect care of it, which is easy, though that's factoring in me using a trick to pause it here and there.
@NovaSquirrel πI got the Anya one but I had to turn the sound off sure to work and I usually forget about it long enough over the weekend she runs away. Always liked the idea more than the execution. Pokemon ended up more my speed
