You have to replace the Chef of an animal restaurant while he is in vacation. The restaurant is on your hands now and you have to make the animals feel happy and satisfied by your services. Feed all the little animals that walk in the restaurant, with the right food they order, as fast as you can. Learn their language so you can feed them with the right meal. Cash in and make profit to go to the next level. Good luck!
