Cloning Clyde

You only need to finish levels 1-24. The challenge levels do not matter towards this. The "Clyde Kong" level is above main doors, up the ladders. Finish the level/game for the achievement.

The level runs utilizes all of Clyde's mutations, so of course it would be easier to use "Mutant Clyde" instead of needing to mutate multiple Clydes. You get the Mutant Clyde cheat after finishing each course (1-24) and challenge (1-10) under par time.

You must complete levels 1-24 plus the 10 challenge missions, then go up the ladder above the doors (leading to the different levels on the map) and enter and complete the CLYDE KONG level.Simple to do as you have Mutant clyde,which is all of the adaptaions of clyde rolled into one. Once completed the achievement unlocks.Hope this helps
