This round, purple and farting creature is called a Puffer. It lives happily in deep caves, but has one problem: it is unable to stand its own smell for too long. So it needs to travel continuously to leave the smelly caves as soon as possible. All to escape its own odor.
When the puffer doesn't travel, it floats through the air like a balloon. Its ability to change air into gas and releasing this gas, helps him moving around in the dangerous caves. While releasing its gas, it will grow smaller to fit through the narrow passages. Perfect for avoiding sharp rocks.
And you better avoid these! Because pointy rocks and other dangers will hurt the small puffer. This results in loosing a life per accident.
Can you help the puffer avoiding its own stench? You do this by escaping the caves in all the 60 levels. But be warned: there will be a lot of gas in this addictive game!
