The buddies are working at a cafe with their hip boss, Koumori!  Time to keep the vibes groovin' and the coffee coming!
Be friendly and keep it groovin', huh?
التصرّف بودّ والحفاظ على ذبذبات منسجمة إذاً؟
Freundlich sein und grooven, ja?
"Sé amistoso y da buenas vibraciones".
Être souriant et avoir
la grosse pêche, hein ?
Socievolezza e in alto l'umore... eh?
Ser amigável e animado, certo?
Быть дружелюбным 
и излучать радость, да?..
