Despite its wide catalog of beloved characters, Disney’s mobile games (like the great Where's My Water?) have often introduced their own leads created especially for each game.

Mittens is strung together by adorable animated cutscenes, which show the irascible titular feline attempting to woo a prissy purple kitty. Every time Mittens tries to give her a gift, she inevitably grows distracted by some other potential sign of affection. As a result, each set of stages introduces a new target gift to win her heart, like milk, balloons, and chocolates.

Want to quickly switch between multiple accounts? Prefer to filter out certain tags, photos, or even entire users? Gramatica has your back.
