Kids Blue Dinosaur Onesie Costume with Hood and Tail

What's Included

• 1 × hooded jumpsuit with attached tail in royal blue and grey, front zip closure

The Kids Blue Dinosaur Onesie Costume is a full-length hooded jumpsuit designed to turn any child into a roaring prehistoric creature. Sized for ages 3–10 years, it delivers instant cartoon dinosaur vibes with bold primary colours and playful details.

Royal blue body with a light grey belly panel running down the front, red segmented crest crowning the hood, and a row of red triangular spikes marching down the spine to the tail tip. The hood is shaped as a dinosaur head with white teeth framing the face opening, yellow eyes, and red brow ridges. A long attached tail extends from the back, finished with the same spike detailing.

Key Features

• Hooded dinosaur head with white teeth and red crest detail
• Red triangular spikes down the back and tail for that classic dino silhouette
• Front zip closure for quick changes before or after the party
• Long attached tail with grey, blue, and red colour blocking
• Two-tone belly panel for a friendly, non-scary cartoon aesthetic
