Funny Leprechaun Tricks and Traps for St. Patrick's Day Fun: Oh no, a Leprechaun left footprints in the bathroom!

Oh no! Did the Leprechaun escape... through the toilet?

10 Mischievous Leprechaun Tricks and Pranks

1. Green Toilet Escape

My kids got a kick out of this one, thinking that the leprechaun escaped through the toilet! Simply use green food coloring in the toilet bowl, and create green footprints on the seat with washable paint. It’s very simple to make leprechaun footprints, just use the side of your fist for the foot, and fingerprints for the toes!

2. Door Barricade

That trouble-making leprechaun may attempt to block the kids’ bedroom doors with green crepe paper and shamrocks. This is a quick one to do the night before St. Patrick's Day, while the kids are sleeping. Include green or gold balloons to add to the fun.

3. Mirror Notes

Use a green dry-erase marker or window marker to leave a festive message on the bathroom mirror, or print one of these backward leprechaun notes from A Little Lair or Busy Bees and have the kids place it in front of the mirror to decode.

4. Windshield Rainbow

Here’s a fun prank to play on the ride to school or a St. Patrick’s Day outing. Create a rainbow that magically appears when you turn on your windshield wipers. Make sure to use washable paint, and put the rainbow on the passenger side so you don't block the driver's vision.

5. Green Milk

This is a classic and super simple leprechaun trick: add some green food coloring to a gallon of milk or a glass of milk for a morning surprise. Pair it with a bowl of Lucky Charms for the ultimate St. Patrick's Day breakfast.

6. Green Lighting

This is an easy prank that’s sure to get a laugh: swap a few lights with green bulbs, or color your regular light bulbs with a green sharpie. (You won't even need to clean up; the color fades with the heat of the bulb over time.)

7. Leprechaun Cookies

Use edible spray paint to turn Oreo cookies gold to resemble gold coins or shillings. Combine these with the rainbow of streamers idea found below for a fun surprise.

8. Rainbow Streamers

Create a rainbow made of streamers, such as this one by Natalie Menke. At the end of the rainbow, leave a pot of gold (like gold Oreos or chocolate golden coins) or other goodies for the kids to enjoy.

1. Lego Leprechaun Trap

Grab your green Lego bricks and create an enticing house that will lure the leprechaun in (we love this one from Fun Money Mom), or build a rainbow staircase out of Lego bricks leading to your trap (such as this one from East Coast Mommy) because leprechauns can’t resist a rainbow!
