DND Terrain Christmas Tile Puzzle

I made my own version of the floor puzzle in the back of Tasha's Cauldron of Everything. If you have that book take a look. I made this one specifically for a Christmas one shot for my family. They really enjoyed it and I hope you do too.

Here's how it works. When a player steps on a letter in a specific word it triggers whatever the list below says it does. But basically put the party on one side of the the floor and a door on the other side. Once they step on the word JOY it unlocks the door. The effects below and be taylored to your party. Up the damage or just make it silly. but

Puzzle Effects

Lights - Blinding Christmas Lights. Character is blind for a round
Gift - a Present appears (you decided where and whats in it)
Snow - 1/4 of puzzle gets covered with snow
Bells - 2 Bells come down and smash together on someones head. DC 12 can dodge out of the way
Carol - Carolers appear and sign a song that hurts the characters head
Feast - a Feast appears at the end. Characters that eat it will gain extra health or strength
Toy - small toys appear and make it difficult to move. Possibly take 1d4 damage from stepping on legos.
Frost - A cold wind blows. PC takes 1d4 cold damage

Merry - heals for 1d4 damage.

Joy - Unlocks the door on the other side.

Printing instructions:
This will take the entire bed. Its a 10in by 10in grid. So make sure its clean. I didn't clean mine and it came out great but just want to make sure you know what you are getting into.

Let me know the best way to make this modular. I'd like to make this so it can be DIY puzzle.

Heres a guy who made this out of foam. He made his own version.https://youtube.com/shorts/Lu-AwzHtWVY?si=QGD208KA1JpA5LyV
