The Littlest Strongman of Bedrock

Before there were superheroes, there was Bamm-Bamm Rubble — the prehistoric toddler whose strength was the stuff of legend. Now your little one can channel that caveman power straight into Halloween night.

Club-Wielding Cavekid Style

The costume captures Bamm-Bamm's signature look with a tan animal-print tunic that's unmistakably Stone Age. The rough-hewn, prehistoric aesthetic brings the classic cartoon to life in an instant.

A matching hat tops off the ensemble, giving kids that wild, lovable cavekid silhouette straight from the streets of Bedrock.

Yabba Dabba Doo, It Fits

Designed with young trick-or-treaters in mind, the costume is sized for easy movement so kids can roam the neighborhood with all the enthusiasm of a pint-sized prehistoric powerhouse.

Comfortable enough for a full evening of candy collecting, it holds up through all the excitement that Halloween brings.

Bring the Whole Rubble Family Together

Bamm-Bamm is even better alongside Pebbles, Betty, Barney, and the rest of the Flintstone crew. This costume is a natural anchor for a group or family theme that fans of all ages will recognize and adore.

Whether kids grew up watching reruns or discovering Bedrock for the first time, the charm of Bamm-Bamm is timeless and universally beloved.
