What you need:

Upside Down, spinning room, dog food, lots of sausages and orange juice, a field, broken telephone, video games and gravy

What to do: 

1.  First, provide your stange strange unicorn with an environment that continues on spinning and is upside down to confirm that your strange unicorn is feeling at home. This will allow your beast to get enough sleep since they hate normal things.
2. After, allow your crazy creature to munch on dog food and chocolate wrappers and sip fizzy sausage mixed with orange juice to create a healthy healthy happy unicorn otherwise your unicorn will rot and will gain crippling depression.
3. Later on, provide your strange unicorn with the chance to spread the wings on it’s gluteus maximus and do thousands of pushups and situps daily. If you do not do double exercise on mondays then your bast will go nuts and turn into a killing machine.
4. Finally, do not ever once in your life discard a broken telephone since strange unicorns use their magic and make it grow and use it as a bed. Also ensure that they are allowed to play video games for an hour at lunch so it can calm down.

Warning : unless you want to be shattered pour gravy over your unicorn’s horn otherwise it would explode and destroy everything you own and you will die and be internally sad in the afterlife.
