Unicorns are a type of Beast enemy in Whimsyshire and Whimsydale in Diablo III.
In-game

They are tougher and faster than Cuddle Bears, but attack in fewer numbers, using their horns and hooves. Their colorful appearance was seemingly inspired by the My Little Pony franchise, giving Whimsyshire its second name: Pony Level. Their melee blows are slow, but hit hard.
Unihorn and Dream of Piers are non-combat pets available to players.
