About The Rock III
The	definite article

III	noun	Roman numeral equivalent to Arabic "3".
There are eight Custom Levelz with the name "The Rock" sharing the theme of having a 'rock' (of some type) that startz rolling at the loading of the CL, and must continue rolling until (nearly) the end of the puzzle, performing certain actionz that a Grunt cannot perform, due to the terrain that must be crossed in performing those actionz. This Custom Level is done in the "Trouble In The Tropicz" graphicz set, which is the third of eight setz of Tilez provided, so it has the number "3" as a modifier to the level title. Guenter designed the original "The Rock" Custom Level, and otherz have 'copied' the theme, using the other graphicz setz, and adding a Roman numeral designation: (the link to the other puzzlez in this seriez) 1 (I) Rocky Roadz (The original doez not have a designator.)
