Buster pretends to be ill so NOKSU runs around caring for him, but when he asks Dr. OK for help Buster knows his number’s up.

NOKSU's name means 'be yourself', which is how he and his friends face everyday experiences and have fun learning life's little lessons. Noksu's natural curiosity and extrovert character propels him from one adventure to another and wherever he goes, tiny Nupi buzzes along too.
