You will need a shaded space, snow flowers/ carrots/ lettuce and time.

First, find them a shaded space with snow on the floor as in the wild they would live on the mountains. Afterwards, you must find the time to groom it since there hair knots easily. This must be done often because it is hard to undo when it has been there for a while. Penultimately, make sure that they only eat lettuce, carrots and flowers as they are allergic to everything else. They can only drink water.
Finally, you must walk them once a week. As a result, your Pegasus will be fit.

Do not feed anything that is not said on this sheet because they will die.
