I have the Power Palz frog. It evolves a few times, but if you dont marry him/her, then it will die in less than a week. (It will get old and wrinkly then die.) The animations aren't great in my opinion. I also noticed my frog only made a mess and got hunger, but didn't need to train, play with him, so it was getting boring after a while. If you have 2 of them, then you can connect them via infrared, marry them and have weird dino/frog, cat/dog mutant babies. If it's really cheap buy it if you want it, but it's not the best dino V-pet.

And no, you can't name it, if I remember correctly, and you will get a random gender, either a boy or a girl. They have different games and training depending on the gender. Hope this helps.
