Anything Dr. Seuss is fun to work with as a theme since everything is so colorful and whimsical. Which is good, I guess, since Lorax themed partyware has not been produced so you're on your own.
I opted for basic yellow tablecloths with orange plates/napkins and decorated simply with orange balloons adorned with the Lorax face.
Eh, his face is a bit spread out... poor guy :)
Helium is at an all-time high but children dig balloons. And they do make a room more festive. I got the face cut-outs here for FREE: http://www.thepartyanimal-blog.org/lorax-birthday-party-theme/
I also did a photo wall with the trees and had mustaches to use. I downloaded the mustaches (from the link above) and just taped it to a yellow straw I ordered for the cotton candy. While most young children won't ham it up in a "photo booth" like adults, it still gives the opportunity for a fun family picture.
For food, I went with 1) inexpensive 2) kid friendly 3) easy for a crowd. You guessed it, pizza! For dessert, we had cupcakes. I ordered a mix of chocolate and vanilla and asked for all orange frosting. I made these cute cupcake toppers to put on each - just printed them on cardstock, cut, and taped to a toothpick. Also found at the link above!
The trees in The Lorax look JUST like cotton candy to me.
So though we didn't need anything else, I had to add cotton candy to the line-up. I ordered yellow striped paper straws from Amazon to use as the tree trunks. To make the "trees" stand up, I covered a box with wrapping paper and punched holes in the top. Add a fluff of cotton candy to a straw and you're good to go!
There you have it! Relatively easy, inexpensive, yet festive Lorax themed movie night. Huge thanks to Nicole @ The Party Animal for the downloads!
