Brother Kojo is the monk in charge of the Clock Tower. When the player first meets him, the clock has stopped working, due to the fact that the four cogs that keep the clock running have been taken. He also makes watches, but due to the clocktower being so near to Ardougne no one actually needs them, so he has far too many. As a result, he will happily give the player as many as they need for free.
- Brother Kojo is the solution to the hard cryptic clue: He knows just how easy it is to lose track of time. The answer to the challenge scroll "On a clock, how many times a day does the minute hand and the hour hand overlap?" is 22.
