Wierd jackhammer glitch!
Put on any hardhat and hold D! you will freeze!
Freeze dancing!
To freeze dance hold down D. If you do it with special items you might get some wierd effects!
Walk on pathways:
Stand somewhere far enough away from the door to another room so you will have atleast 6 seconds after you start walking. Then click on the path to the next room. Quickily open your penguin mail thing and keep it open until you think you stopped walking. Open it and you will be standing between 2 rooms!
Super noise maker!
Put on a bell or whistle or both and hold D! Annoying isnt it?
