Well, of course you do know that leprachauns do enjoy their whiskey. But I believe they also enjoy eating their potatoes with a side of greens. What's funny is they have been known to nibble on fairy bread as well.
As for the unicorns, that depends on what breed of unicorn you are asking about. Certain ones can or some have the teleportation bred out of them.
leprechauns eat mental health and unicorns cant teleport because they arent real, but because they arent real, they cant be really perceived as being in one place, but can be perceived anywhere and doing what ever
