PokéCrossing! I might even make more later :D
This would be so PERFECT. You could “collect” Pokemon by helping them out with errands. After you do enough for them they would start following you around and help you with other errands/picking weeds. Of course you’d have to keep them happy/entertained, or else they would go back home.
Also, the Happy Room Academy would actually be Team Rocket (and their tacky decoration sense). Meowth would be Mr. Nook, always playing you for more money, and Wobuffet would be Mr. Resetti. Make this HAPPEN Nintendo.
