Like Tina and Luci, Carlos and his little brother, Juan, who was played by Michael Krost, are of Mexican descent. Even though he and Juan are brothers, they are only seen together in two episodes of Season 3; If the Shoe Fits... and Any Way You Slice It, both of which Min appeared in. He also has a cat named Fluffy and a bowl of goldfish (named Super, Dee, and Duper; a pun on Barney's famous phrase) for pets as seen in Our Furry, Feathered, Fishy Friends.
Carlos has his little brother Juan, his mother, his father, and a grandmother in his family, as mentioned in the episode "Room for Everyone". He had painted a picture of himself and his family in the same episode.
