Unicorn

Unicorn are the new creature introduced in the PC/Mac version of The Sims 3: Pets and they are not available on the console versions of The Sims 3: Pets. It was announced for the first time on The Sims 3: Pets - Gamescom Germany Trailer.

Overview
Wild Unicorns appear normally at night and disappear at day. At 8:00 PM there is a 33% Chance a Wild Unicorn will appear in the Neighborhood. They usually spawn at Fishing Type of Lots and on the map. No matter what traits a Sim has, a big shining cloud may appear above a lot. Under the cloud is the Wild Unicorn, with sparkles coming down from the Cloud and onto the Unicorn. At 5:00 AM the unicorn will disappear in a burst of sparkles, as seen below.

Sims can try to tame Wild Unicorn to join the player's household. However, the Sim will need to be best friends with it first, and also be 'best friends forever' with 3 household animals. If the Sim doesn't abide by the unicorn's wishes it will decline the Sim's request. Unicorns like gardening and they often bless plants if they are near them; they almost never curse plants. Once a Wild Unicorn has been invited into the family the floating cloud above it disappears. Once a Wild Unicorn is invited into a Household and it accepts, another Unicorn will be generated and will become the new Wild Unicorn, since there can only be One Wild Unicorn Per Neighborhood at any given time. You can have multiple unicorns in your household. Just like a Sim can, a unicorn can be added to the active household through testingcheatsenabled. After entering the cheat, the player can shift-click on the unicorn and select "Add to household", which will immediately add the unicorn to the family.

Unicorns are very mystical creatures; if they stand still, eat hay, graze, or drink water from a pond, a rainbow will shoot from its horn or a small plant will grow in front of its right front leg which will turn to leaves that can be carried away by the wind and disappear. If the Graphic Options are high it can be seen that the Unicorn's coat glows.

Appearance
Unicorns may look a little like a normal Horse, however there are some traits in their appearance that make them different from Horses. A Unicorn has a horn on its head which is the main trait of their appearance. Unicorns may have three coat shades: Black, White and Grey. A unicorn will also have a different tail and will have a goatee growing from the their bottom lip.

Unicorn Offspring
Unicorns can mate with other Unicorns and even with Horses. If a Unicorn mates with a Horse there is a 50% Chance the Foal will be a Unicorn. and if both parents are Unicorns the foal will be 100% a Unicorn as well. Unicorn Foals have no access to their Unicorn abilities. However, when they gallop the magical sparkly trail is there, but they don't run fast like an Adult Unicorn, instead they run the same as normal Foals.
