Bamm-Bamm Rubble is a character on Yabba-Dabba-Dinosaurs! He is very adventurous, and is the complete opposite of his BFF, Pebbles. He is portrayed by Ely Henry.
Background
Bamm-Bamm is the adopted son of Betty and Barney Rubble after they found him left on their doorstep. After meeting his next-door neighbor Pebbles, he falls in love with her. Bamm-Bamm's "nickname" came from a note left in the basket, causing Barney and Betty confusion over the strange name.
This was explained when Bamm-Bamm yelled the phrase "Bamm, Bamm!" and swung his club. Bamm-Bamm's excessive (and sometimes misused) strength was often a source of humor in the episodes the toddler version of Bamm-Bamm appeared in. Unlike Pebbles, Bamm-Bamm was past the crawling stage and could be seen in a few episodes trying to help Pebbles walk.
