Change random words into pony names! To do this, you take a word or name, which can be anything, and turn it into a pony name by changing one letter per post (it doesn't have to make a word.) You can add, remove, combine words, or change a letter into another each time. Spaces are not included, just add the next letter in a word. (Starlight --> Starlight G). You can also combine the words using a turn or remove the last letter. (Starlight Glimmer --> Starlightglimmer).
When you successfully turn a word into a pony, the user picks another word and pony name to change it into.
Again, any word is valid, and you can even make it harder for other users to make the word.
Example:
Start: Tree to Fluttershy!
