All of these cheats are very very very good cheats so i suggest you look at them!

1:(walk on walls 1 nobody can see it) Turn the screen to 1000%… then keep clicking on a wall… go back to 100%… AND PRESTO your on the wall!!!

2:(sharp shootin!) Go to the ice rink… Click on top of the puck… then click in the goal poast… and GOAL its in!!!

3:(special dance) Take all your cloths off… put a special dance item on but dont click x… and dance and you wont be holding the item!!! Note: This has been fixed.

4:(walk on walls 2 everyone can see this!) Click on a path that leads to another room (i suggest the ice rink going into the snow forts) then QUICKLY click on the penguin mail icon wait for 10 to 15 seconds and your on the path but it looks like your on a wall!

5:(super mega ultra cheat!!!) use a NON MEMBER (this is when being a non member comes in handy!) and log in… in the first 5 servers click one thats NOT full then click on the place where there was a full server and youll see this white screen! You can re-take your secerete agent test too! Its cool! (oh and to have the white screen forever click on penguin mail!
