The colorful T-Rex party has one rule: more is more. Every color should be represented. Red, orange, yellow, green, blue, and purple all together, all loud, all at once. This is not a subtle theme — and that's exactly the point.
Bold Decorations That Mean Business
- Rainbow balloon arch — a full spectrum arch is the ultimate statement for this theme
- Colorful T-Rex balloon accents — dinosaur foil balloons in every color woven through the arch
- Bold color-blocked tablecloths — different bright colors on each table
- Dinosaur footprint trail — giant painted footprints leading guests from the entrance to the party
- "STOMP CHOMP ROAR" welcome sign in rainbow letters — the most joyful welcome imaginable
Colorful Food for a Colorful Crew
- Rainbow fruit skewers — strawberry, orange, pineapple, kiwi, blueberry, and grape in rainbow order
- "T-Rex Stomp" punch — layered colorful punch in a clear bowl
- Colorful dino cookie platter — T-Rex shaped cookies in every color of the rainbow
- Rainbow layer cake — multicolored layers inside, bold colorful frosting outside, a T-Rex topper on top
Activities for Bold Little T-Rexes
- Roar contest — loudest roar wins a rainbow prize
- Dino stomp obstacle course — stomp through a colorful course
- Dinosaur Adoption Ceremony — each child receives an official personalized dinosaur adoption certificate with a colorful T-Rex to name and take home. Kids choose their dinosaur, fill in the name on their certificate, and become its official adopter. It's the most memorable 5 minutes of any dino party.
The Creative Take-Home Experience: Paint a Rainbow T-Rex
Give each child a plain wooden or foam T-Rex cutout and set out every acrylic paint color available — the whole rainbow. Kids paint their T-Rex in whatever color combination they want — realistic, rainbow, tie-dye, polka dot, anything goes. The result is always spectacular and always completely their own. Add their name and the party date on the back with a paint pen and send home as a wall hanging or shelf piece.
