Laa-Laa is yellow and her antenna is a squiggle. She is very happy and likes to dance. Po is red. She is the smallest Tubby and speaks Cantonese. She rides a scooter.
Babies like to see babies, and just about everyone warms up to a happy gurgling one.
Davenport's research found that babies have trouble doing both at the same time. When a trumpet emerges from the ground, the Tubbies watch it, and children can expect to hear a voice. The adult voices speak clearly and rhythmically, providing examples of correct speech. The Tubbies' baby talk imitates the early words of children acquiring language, and allows young viewers to identify with their alien cohorts, who are no smarter than they are. All of these things replicate the kinds of activities parents do with young children.
