The monster he made totally on his own. But with Dino I had to help him out in making the legs and the trimmings on the back.
Edited to add : The 'Monster' was not supposed to be a monster in the first place. He was trying to copy a goat from one of his books. But when he completed it he said "Mumma, yeh to goat nahi hai. Yeh to monster hai!" :D
