Gabriela (motion captured by John Munro Cameron, voiced by Alice Dinnean) is one of the three best friends Sid got. Unlike her friends, Gabriela is the most sensible character and often comes up with the most reasonable jokes during Good Laughternoon. She is the most authoritative figure of the quartet, often being the leader of the group activities. She is usually the one that likes to come up with playing Pretend, always opting to be a "mommy" parent. She can allegedly read and potentially help with others in her group that don't understand something in a lab or any other academic activity. She rarely comes over to Sid's house to have a play date with him but does more than the other two kids and must have her parent's permission to do so. She has an older brother named Mateo.
