Zigzag is a little wizard.
However, he isn't a real wizard yet.
One day, dad gave him a question.
He said to be a real wizard he should find the way home alone.
"Our home is the only apartment 'Cicle' in 'Triangle wing' that past
the 'Quadrangle' apartment complex."
Dad marked a starting point with a magic pencil.
Then, by magic, it moved alone, drawing a line.
"This magic pencil will draw a line segment wherever you arrive."
dad said.
