Have you seen the new Teenage Mutant Ninja Turtles movie yet? If your child’s a fan too, then infuse their next birthday with a little Turtle Power! If you haven’t seen our blog post about TMNT party supplies, you can see it here. Now, we’ve searched the sewers for the best DIY Teenage Mutant Ninja Turtles decorations and recipes around, and we’ve found 10 that, as Michelangelo might say, are totally radical. Keep on reading to see our list of top TMNT tips!

Decorate with masked paper lanterns.

Green paper lanterns can be made to look just like the friendly faces of Leo, Don, Raph, and Mikey. Use colored crepe paper or tape to make the masks, and add some googly eyes on top!

Balloons can be masked, too.

It’s the same idea, only this time the eyes are holes cut into the crepe paper itself. Use these as a centerpiece on the table, or fill with helium and make a TMNT balloon bouquet.

And cups.

TMNT party rule #1: if it’s green, and if it qualifies as party supplies, it’s getting a ninja mask. This time, the masks are colored ribbon and googly eyes, but wrapping paper would be another good choice.

Don’t forget to mask the kids!

With all these masked decorations, we nearly forgot about TMNT dress-up! The idea for these felt DIY ninja masks comes from theelise.com – the how-tos are in Norwegian, but the photos along with the tutorial make it crystal clear!

Make your own sewer slime.

Slime is a great DIY toy for the kids to play with, and it will help them “mutate” to get ready for the TMNT party! ScienceBob.com has two great homemade slime recipes to try – this one is the classic cornstarch and water mixture, and this one is based off of white school glue.

Make TMNT cookies!

These fun cookie designs were made by Mary Dunne of Cookies by Mary. She used a standard circular cookie cutter for the heads, shaped them a little by hand, and used an “awareness ribbon” shape to create the tied masks.

Play “Pin the Toppings on the Pizza.”

What do the Turtles love more than almost anything? Pizza, of course! Make a pizza-shaped game board like the one above with poster board or construction paper. Have the party guests, blindfolded, try to stick pepperonis (paper circles with double-sided Scotch tape) to each slice.

You can also pin the masks on the Turtles.

The object is the same in this party game – who can get the mask closest to the Turtle without looking?

Display a buffet of green candy in Turtle-esque containers.

Green taffy, gumballs, and licorice look great like this. Mask some tall glass jars or apothecary jars with colored crepe, and arrange on the table as a centerpiece.

Create DIY TMNT party favor bags.

Using a plain green paper gift bags as a base, add the Turtles using pieces of craft foam. Fill them up with your child’s favorite favors, and hand them out the guests so they go home happy!
