On the night of a festival, the Marker duo Walsh and his daugher Lynda return, and Memempu receives a surprising gift. Will she finally be allowed to pursue her dream?
They say there was a Marker called 
Urorop who went all over the Labyrinth
يُقال أنّه كان هناك مُنقّبة تُدعى أوروروب
عبرت إلى كلّ أنحاء المتاهة
Diese Marker-Dame Urorop
Dicen que la marker Urorop
recorrió el laberinto
Dicen que la marker Urorop
ha recorrido todo el laberinto
La traceuse Urorop
a traversé le labyrinthe
Si dice che la marker Urorop
 abbia girato tutto il Labyrinth
Dizem que a Marker Urorop 
passou por todo o labirinto
Да, девушка-маркер Уророп!
