If you draw a larget steep arch then when you are at the bottom connect the two points w/ what look like McDonalds arches. It is a primitive ghost but the system does recognise it.

There are two other gestures besides Pac-Man you unlock in levels that will be used later in the game:

Arrow - Clear Chapter 4
Bomb - Clear Chapter 8

You can only do this gesture in the sketch book mode. To perform this gesture, draw all around the edge of the screen and it will be a window wiper.

You can only do this gesture in the sketch book mode. To perform this gesture, you draw an 8 on its side, also known as an infinity sign. If you perform this correctly, the "butterfly" will flutter around the screen.

draw the letter P and it will bounce of screen like a pogo stick

You can only do this gesture in the sketch book mode, which you can access in the Gallery. To perform this gesture, you need to draw a cloud. Just draw a circle using a series of "curly" motions. If you succeeded the lines that you scribbled will turn dark blue, and rain will start to pour out of the figure.

In the Sketchbook found in Gallery Menu, you can draw a treble clef, which will turn red and chime. This gesture can only be done in the sketchbook.

Book two is an extra set of 12 chapters. These chapters are much harder you have to complete the game to unlock book 2.

After you complete chapter 4 and learn how to draw the arrow gesture, you can fire arrows at pac-man in the sketchbook. Simply draw the arrow facing at pac-man and fire. When it goes past him, he'll lean back a little and scream "wa wa wa."
