You are a boy/girl in the care of father Wally, he is kind and you see him as your father, Julie, Barnaby, Sally and the others were playing outside in the green field where there was nature, you were curious/or went to see where there was a mural which was very high... you were accompanied by Julie who said

Julie: I wonder what opens on the other side!

but they hear a familiar voice

Wally: dear... you know you don't have to come here... what are you doing here?
