Philop is one of four children belonging to Gertrude: a widow whose house is located just outside the western gate of Varrock. Philop can be found with his brother Kanel inside Gertrude's house playing with toys. The two older children, Wilough and Shilop, are found in Varrock Square.
Philop does not have any use in-game, although the player may talk to him to initiate a humorous conversation in which Philop repeats everything the player says until the player gives up and leaves.
