Though the AI for the horse is quite frustrating as it very frequently walks/runs away just as you're attempting to put your crops in the saddlebags (which double as a portable shipping bin). The livestock in this game are cows, chickens, and sheep. Cows produce milk. A cow with 8 or more hearts will produce Large Milk and a cow that has less then that will produce Small Milk. They become grumpy and stop producing milk for three days if the farmer is unable to feed them (due to the farmer getting a cold or a storm/bad weather) keep feeding them and brushing them and after 3 days they should be happy again. You can have four cows. Chickens produce one egg per day, unless grumpy. Keep feeding them and after 3 days they should be happy again. You can have four chickens. Sheep produce wool. When your sheep have a higher happiness rating you'll be able to get large pieces of wool, which sell for 250G apiece. As with cows, they become grumpy (and stay grumpy) for three days if the farmer is unable to feed them, keep feeding them and shampooing them and after 3 days they should be happy again. You can have four sheep. They still produce wool even if grumpy. Sheep will regrow their wool every 9 days. There is a wide variety of tools in "Harvest Moon 2 GBC". Tools are used to carry out chores, care for livestock, and tend to crops. On release, "Famitsu" magazine scored the game a 30 out of 40. "IGN" rated the game at 7.0, or "decent", saying that the game world is much bigger than the first "Harvest Moon", and the farming much improved, but the dating sim aspect of the game is greatly missed.
