Este robot recoge los juguetes que se encuentren dispersos/desordenados en la habitación del niño o niña.  El robot consta de 4 articulaciones (RPRR) y una herramienta, que le permiten alcanzar los objetos que almacenará en un compartimiento del robot, tal y como se observa en la figura. En su parte central dispone de una pantalla, la cual muestra alrededor de 20 frases diferentes en idioma inglés o español. A su vez, mediante los parlantes que dispone en su cabeza, se podrá reproducir la frase correspondiente y canciones
