'The GilsCarbo family lives the simple life. Eduardo expresses his passion for music and Carlotta joyfully cares for her family. They love their happy baby, Goopy, and find his early obsession with cowboys and plaid endearing.'
The family shares its name with Goopy GilsCarbo, who is a townie from Pleasantview in The Sims 2. The game strongly hints at a connection, and strongly implies that the toddler Goopy from Monte Vista is the adult Goopy from Pleasantview. However, it does not formally show a relation between the adult Goopy and either GilsCarbo family from The Sims 3, thereby leaving any theories about possible relationships up to individual players.
