A token is a collectible special item added in v1.48 on September 30th, 2011. They are the first and only 3D items in the game. Tokens are used as an alternative way of completing a level. There are six different designs: a skull with six stars around it, a pizza slice that looks like it's falling or crashing on the ground, a pentogram, an axe surrounded by nine dots, a bowling ball knocking four bowling pins over with a star in the top middle, and a peace symbol.
When a token is collected, an 8-bit sound is played, similar to the one used in Super Mario games when coins are collected, only the pitch is lower. When all the tokens in a level are collected, the level ends in exactly the same way as when a character crosses the finish line, along with the triumphant fanfare and the text saying "VICTORY".
For the first two weeks of use, there was a glitch, where when a player restarts a level, the token count in the top-right corner of the screen would double or even triple. This small bug has been rectified and the number showing the token amount required for completion now stays the same.
It is rare for a level to have tokens as a method of completing the level; the level maker will most often put a line of tokens but also have a finish line.
Secondary characters can collect tokens as well and complete levels this way even after the primary character has died.
If your character is alive, removed limbs (such as torn off arms) can also collect tokens.
Tokens spin clockwise in 3D before they are collected.
Putting a huge amount of tokens in the level editor will cause the level editor to either freeze or crash.
Putting multiple tokens on top of each other results in a louder noise when collected.
Like the boost, even though this is a non-interactive item, it will still count towards the shape limit, not the art limit.
