Spikes are a form of danger. When the player's Sack Person steps on them, they are instantly impaled. They are seen mainly in The Wedding and in The Islands. In Create Mode, they come in two varieties, large (three spikes) and small (one spike). The different spikes are basically the same, only one is 1 spike, big spikes have 9 spikes. While being very difficult, there is a possible way to "hop" straight across spikes, you must jump as soon as you touch them. This is usually an accident as result of a player attempting to "ace" a level nervously taps their X button. This glitch probably won't result in Sack People achieving their wish of jumping over their troubles. This glitch may also work on electricity and fire.
- During The Creation Stages,when Sackboy fell on the spikes he would be impaled,but creators thought it looked too violent so they changed it to its current animation.
