RainbowTrail is a plugin that randomly generates a wool block (all 15 colors) underneath the player!
WARNING: This plugin is experimental and is not meant for regular servers! Use with caution!
Use /rt, or /rainbowtrail to enable/disable your rainbow trail! The player will need OP (/op) or the permission "rt.use"
The blocks created can only be seen by the activator of the rainbow trail, and generates client side only blocks, so NO server grief!
