Click-Clack, often called Clacky by Garby, is a Rotilian Reptool who is clumsy, pantophobic and tends to fall down a lot. He is normally concerned with running away and hiding, in his own words, tending "to avoid danger at all costs". He even stated that he uses "Tool tips" that he hopes will help him survive in the world, and once said that he "knew a Tool who lost three and a half bits to frostclamp". Sometimes, he even gets scared enough to lose all of his own bits, and is teased by the other Tools for this, particularly Ace. Despite his cowardice and constant worrying, he has managed to pull off a few acts of bravery from time to time and he has proven that he can work well under extreme pressure. He is also somewhat timid about voicing his ideas.
