Tulunk Village

A lot of time ago, I found a game that is called "Hamster Monogatari Collection".
In it I found a game that i can't understand because it's seems like horoscope, but in japanese, a puzzle game and another one that is a monster RPG.
I try to found information about it but...I can't found anything T^T
Does anyone know it (or something about)? There's a way for take the monster sprite from it?

I'm not sure, but I only found that there's a lot of game of this saga and one I thing is for N64...I played the GBA version...

I take some screens...

I've got this game, but I haven't played it yet..x3
GameFAQs has a page for it here.
There are a quite a few other games in the series too. The original game was for the N64, but there are about 4 or 5 gameboy advance games and also a gameboy color game. I think they're hamster raising sims/adventure/puzzle games? They seem to be a mix depending on the game.
