BJ is a 7-year-old yellow Protoceratops with a green belly and purple spots and freckles who wears a red baseball cap and red high-top sneakers on his feet. He is Baby Bop's older brother and Riff's cousin and best friend. His theme song is "BJ's Song".


He is very athletic and loves sports like baseball, soccer, football, etc.


BJ is yellow with a bright green tummy and purple spots. He has three purple freckles on each cheek and some spots on his nose, which looks pointed at the tip. His tail curls up instead of hanging down like Barney and Baby Bop's tails. He also has three fingers on each hand. When he first appeared in Season 2, BJ was as tall as Barney, and his mouth moved more. Throughout the years he was shortened, and starting in Season 3 his mouth was easily moved by BJ just bobbing his head up and down. BJ has three strands of exposed in front of his red baseball cap.


He is very valiant at most times, but sometimes he makes mistakes and he tries to hide fears. This was shown in the 1998 home video, Barney's Halloween Party when he was shocked by the paper spiders. After learning they were fake, he replied "I knew that, sort of." He had to put up with a stomach-ache twice in the Barney franchise. BJ likes hanging out with his little sister and their friends, but some times he would end up in arguments or fights with Baby Bop. Though they still love each other very much.

Here are the following episodes and reasons for his stomach aches:

Circle of Friends: He ate too many pancakes even after Miss Etta warned him about it.\

BJ's Snack Attack: He ate too much junk food.
