Lego Movie-Themed Birthday Party (with lots of DIY Lego birthday party ideas)Lego Movie-Themed Birthday Party

Both our kids are really into The Lego Movie (remember our Halloween costumes?), and I’ll be honest, I don’t mind. It’s actually a really clever movie, and if they are going to binge-watch something, thank goodness this is one that the hubs and I actually enjoy too. I also didn’t mind in the least when my oldest decided on The Lego Movie as a birthday party theme this year. Lego is a super fun party theme to work with, and inspiration seems endless (you can check-out my Lego Movie Birthday Party Inspiration Board on Pinterest to see some of the DIY Lego themed birthday party and Lego party snack ideas pins that inspired me). Lots of fun (though not overly difficult) DIY projects were involved in the preparations for this party. In addition to including the characters from the movie, I was able to incorporate Lego bricks into the theme, and kept it all in a standard Lego color palette of green, red, blue, and yellow, so these ideas can work for any DIY Lego birthday party, not just Lego Movie themed birthday party ideas! Keep reading to see all the DIY Lego birthday party ideas, including Lego Movie party favors, Lego themed food ideas, details on our DIY homemade Lego party decorations, Lego party games and activities, and free Lego party printables.

Lego Movie party favors:

We have lots of Lego Movie party favors! Some were shared in gift bags, and others were things the kids could make as part of the party activities. For the gift bags, I got paper favor bags (red, blue, and green) from Amazon, and used a circle punch to add circles on the front to make them look like Lego bricks.

Contents of the favor bags included Lego crayons (see more details on this DIY project below), brick-shaped bubbles, brick bracelets, brick candy, Lego Movie stickers, candy wrapped with Lego Movie character art (see a close-up in the Food section below), and loose bricks (see a close up below).

I got a bunch of loose bricks from our local Lego Store and bagged them up in plastic treat bags with a label that said “You are the Special! Master-build your own special creation.” It was so cute to see the kids’ creativity with these!

I made Lego brick and minifigure crayons with silicone molds following the same instructions I used for the DIY dinosaur party crayons here. This is much easier than you’d think, and DIYing them using silicone molds and bulk crayons is a lot cheaper than buying custom-shaped crayons. You can do these for almost any theme, and the silicone molds can be reused for other party projects (candy, Jello, etc.).

Since I also had brick-shaped candy in the favor bags, I found it important to make sure each was labeled so that the kids knew which Lego Movie party favors were candy and which were crayons!

These free printable Lego Movie character masks were a big hit! I just needed to print them, cut them out, and attach ribbons to tie them.

Another of our Lego Movie party favors came as part of one of the activities where the kids got to build (and keep) their own minifigure (see Activities section below).

Lego themed food ideas for a DIY Lego birthday party:

The brick shape theme was fun to work with for our Lego party snack ideas, so we incorporated that wherever we could. We also used the traditional Lego colors of red, yellow, blue, and green for the Lego themed food ideas when we could, and of course, we also called on references to The Lego Movie for the food inspiration.

I was inspired by The Mauve Dinosaur’s Lego brick sandwich idea, which you can see on Pinterest here. Unfortunately the original blog post with the instructions is no longer available, but I made turkey and cheese sandwiches cut into rectangle shapes, then used a bit of cream cheese to stick two circular pieces of bread (cut using the cap from a water bottle) to the top.

Pepperoni pizza can also look like Lego bricks when sliced into rectangles with two pieces of pepperoni on top, and are great kid-friendly Lego party snack ideas!

I had to balance out the pizza with some more nutritious Lego themed food ideas, so we had a “Master-Build Your Own Fruit Salad” station as well. In addition to chopped and bite-sized fruits, I had vanilla and strawberry yogurt for the kids to make a sweet, creamy fruit salad.

Like I did for the previous year’s Minions party, I designed Lego Movie character candy wrappers to wrap Hershey’s Mini candy bars. I included these in the favor bags for the kids, as well as in a bowl in the dessert station. The printable wrappers are linked in the Printables section below.

These didn’t turn out as cutely as I’d hoped, but I made red bricks out of strawberry Jello as “Pieces of Resistance” (to go with the Lego Movie themed birthday party).

Another inspiration from Pinterest (from One Artsy Mama) were these rectangular sugar cookies decorated as Lego bricks in the party color scheme. I used cake frosting (the original idea used cookie icing) and M&Ms for decoration, and cut-out sugar cookie dough, which I cut into 1.75″x3″ rectangles.

The Lego brick silicone molds I used for the DIY crayon favors came in handy for the cupcakes as well.  Using colorful candy melts, I used the brick molds to make DIY Lego birthday party candy cupcake toppers. I was also able to find these building bricks candles on Amazon for the birthday kiddo.

Another party supply that gave me a lot of mileage was Lego wrapping paper. I used it to wrap the water bottles instead of purchasing custom party bottle labels. The wrapping paper was thick and strong, and withheld better than a printable wrapper on standard paper. You can also use the paper as a DIY Lego themed birthday party table runner or table cover.

The other beverage at the party was lemonade (the yellow color matched the Lego Movie party theme), and we called it “Legonade.”

DIY homemade Lego party decorations:

I made this sign using clip-art and Legothick font (which you can download for free here), along with a quote by Princess Unikitty from the The Lego Movie. For those of you who don’t have the movie memorized like we do, these are the rules at her home, Cloud Cuckoo Land. They seemed to be appropriate rules for an awesome Lego Movie themed birthday party too, don’t you think?

The centerpiece for the food display was this 6 made out of some of the kids’ Lego bricks. You can use bricks for lots of DIY Lego birthday decorations, as you’ll see in some of my other examples below.

Also using the Legothick font, I was able to make a few other party signs, such as this “Everything is Awesome” sign, and the “Happy Birthday” banner seen below. The frame for the above was a reasonably priced find from Ikea.

I used more of the kids’ bricks to make a crayon holder for one of the party activities (see more on the activity below). I also used more real Lego bricks for sign holders. I purchased these at the Lego Store (and didn’t raid the kids’ stash), since I had to hot glue them onto green, red, and blue Ikea Tolsby frames. These frames have since been discontinued, but you can find them for resale on Amazon, Etsy, and Temu.

This napkin holder was another of my DIY homemade Lego party decorations using our kids’ bricks, and the beverage napkins came from Oriental Trading (they carry a few cute products for brick-themed parties).

I ordered utensils in the party color scheme and large napkins from Party City, then wrapped the utensil/napkin bundles with a small strip of Lego wrapping paper.

Other party décor included bundles of helium balloons in the party colors (red, green, blue, and yellow).

Lego Movie Party Activities:

Since Lego is such a creative toy, there are so many Lego party games and activities to keep the kids occupied during a Lego Movie party. This DIY “Pin the Pants on the Guy” game was fun for the kids! Honey… where are my paaaaannnnttss?

Another inspiration from Pinterest was this brick bean bag toss game (he original idea was from Stamp with Heather, however her blog post with the original idea and instructions is no longer online). I cut corners and used pre-made bean bags with felt dots glued on top (instead of DIYing the whole bean bag).

For Lego party activities that double as an additional party favor, we had a Build Your Own Minifigure station. I got the inspiration from an in-store activity at our local Lego Store, however, made it more cost-effective by purchasing the parts in bulk from eBay.

I purchased assortments of heads/faces (both male and female), hats and hair (both male and female), torsos, legs, and accessories from eBay (various sellers). Kids were to choose one of each to create a custom minifigure of their own to keep. The kids absolutely loved this activity, and it was great to see their creativity come out!

Coloring pages (using free online printables found via Google search) and crayons are always a cheap way to keep the kiddos entertained!

What’s a Lego party without a station for building?  We brought out a few of the kid’s buckets of loose Legos for kids to become Master Builders and just sit and build to their hearts’ content.

Finally, we had the The Lego Movie playing on the TV in the background.
