The Alien Chainsaw is another "Secret" item in the secret shop that is hidden in the game. The Alien Chainsaw has a thin blade which looks like it is made of clear blue plasma.
It costs 2 billion trimmings in the secret shop. It is the second most expensive item in the shop. It only generates around 200-400K trimmings, which is more terrible than Excalibur which costs 300mill trimmings and generates 1mill trimmings per blade.
The three secret alien items were all designed (but not coded) by Dannyha, a fan of Mow My Lawn.
