It’s a jungle on PlayStation 3 and today it’s a jungle on PlayStation Vita too. Sony Computer Entertainment Japan just released Tokyo Jungle Mobile which has more than 40 animals including the Pomeranian. Humans suddenly left the planet and animals have overrun Tokyo. Your goal is to survive by eating plants if you’re a herbivore and other animals if you’re a lion. After your "hungry" meter depletes your character starts to lose life.
The goal is to survive over a century, which means you’ll need to find a mate and raise offspring. Fields have different environmental hazards like smog in some places and at night you have to watch out for predators.
Tokyo Jungle Mobile costs 600 yen ($6), but if you get it within launch week it’s just 300 yen ($3).
