Pikkarikun (ピッカリクン) are small thundercloud enemies that appear in Wario Land: Super Mario Land 3. They sport an impish face and float above Wario. When they flash, they drop lightning bolts down on him. They are invincible and chase Wario through levels, but cannot go through walls and may get stuck if there is a wall in front of it.
If their lightning bolts hit enemies, they turn into 10 Gold Coins.
Their name comes from pikapika, an onomatopoeia for electric sparkling.
