45 Best Leprechaun Pranks To Play on Your Kids

1. Leprechaun’s Topsy-Turvy Room

If you’re feeling bold, flip small pieces of furniture upside-down in your child’s room while they are at school, giving them the impression that a leprechaun was there causing trouble. You can turn over picture frames, chairs, books, alarm clocks, make a few stuffed animals sit on their heads and even place a cup upside down on your child’s desk. Then, when your kiddo walks in, they’ll see that a leprechaun was there.

2. Mini Leprechaun Messages

Write funny, tiny notes on scraps of paper from a leprechaun. The catch? Write the letters in “leprechaun” handwriting—backward, upside down or in a mysterious code. That way, you can watch your kids have fun trying to decode the silly messages!

3. Sneaky Snack Attack

Leave half-eaten cookies or snacks out with tiny bites taken out of them, as if the leprechaun couldn’t resist nibbling on each one. You can even add a tiny “leprechaun fork” made from a toothpick and some mini foil wrapped treats for extra charm.

4. Green Flowers

Set out white carnations on your table a few days before St. Patrick’s Day. Then the night before, add green food coloring to the water so the next morning your children can see that leprechauns turned the flowers green.

5. Rainbow Mishap

Cut out colorful paper strips in the shape of a rainbow and place them all around the house. Then tell your kids one of the leprechauns “left” a rainbow trail behind him while running off to hide his gold!

6. Missing Lucky Charms

If you have Lucky Charms cereal in your home, serve it to your kids without the cute marshmallows. To do this, remove all of the marshmallows the night before so it looks as if the leprechaun ate them all.

7. Leprechaun Bed Makeover

When your kids are taking a bath the night before St. Patrick’s Day, sneak into their room and change their normal bedding to green sheets and green pillow cases. When they return, they’ll think leprechauns paid them a visit, leaving behind a magical, green-filled surprise!

8. Leprechaun Tea Party

Set up a mini “tea party” with tiny cups, plates, and a stuffed animal or two. Place them in funny poses like they’re having a conversation, and scatter tea bags everywhere. Tell your kids the leprechauns must have run off when they heard you all enter the house after school.

9. Prank Call

Leave a funny voicemail on your phone from a “leprechaun” using a silly voice, saying things like, “I'm stealing all your green snacks—better catch me if you can!” Then let your kids listen to it. Don’t forget to mention your children’s names in the message.

10. Jelly Bean Surprise

Hide a bunch of jelly beans inside your child’s shoes or under their pillow. Then, the next morning, they’ll be surprised by the leprechaun's sweet treat stash!

Funny Leprechaun Pranks

When your children are asleep, carefully place little St. Patrick’s Day-themed stickers on your child’s arms or face. Then, when they wake up, tell them that crazy leprechaun gave them tattoos and tell them to go look in the mirror.

12. Hat Trick

Fill a small cup with green Jell-O and set it upside down. When your kid tries to lift it up, it’ll stick, and they’ll be baffled by the leprechaun’s silly magic trick and then confused when they notice the green Jell-O.

17. Magic Green Ice Cubes

This prank won’t cost anything to do. The night before St. Paddy's Day, make ice cubes, but add green food coloring into the ice molds before you put the tray in the freezer. The next morning, ask your child to grab some ice for their drinks and they’ll think the leprechaun’s magic turned them all green.

18. Sticky Hands

Put a little bit of green slime on the door handles or light switches, so when your kids try to use them, they’ll feel like they’re stuck in leprechaun magic!

19. Create a Mischievous Leprechaun Shadow

Use a green flashlight or glow stick to cast weird shadows on the wall of your child’s room when they are taking a shower or bath at night. When your kid goes back into their room, you can say the leprechaun was up to some sneaky late-night antics!

20. Mini Leprechaun Furniture Prank

Place tiny pieces of furniture all over your child’s room (think matchbox beds or doll chairs) so it looks like the leprechauns are moving into your child’s room.

Take a small amount of rainbow yarn and cut it into tiny pieces. Scatter scatter it around in your house, and tell your kids you accidentally scared the leprechauns earlier when you caught them giving each other haircuts and they tossed their hair around when they ran away.

27. Jell-O Surprise

Pour green Jell-O into a clear container and hide a little toy or figurine inside. Put it into the fridge so it has time to become solid. When your kids dig in and eat it for a snack later, they’ll get a funny surprise when they discover the leprechaun’s little “treasure” hidden at the bottom.
