Oobi

Grown-up! (1x67)

:

Oobi, Uma and Kako imagine what it would be like to be grown-ups. Oobi and Kako say, "Grown ups cool!" but Uma insists, "Kids cooler." They dress up and pretend to be grown-up (firefighters, musicians and business people) and do all kinds of grown-up things. In the end, they decide it's much more fun being kids, even after Oobi sees an astronaut.
