Little Mo was a dealer of various merchandise found in Lumbridge during the 2015 April Fools event. He requested the player's assistance to deliver packages whilst he took a highly coveted artefact to the Varrock Museum. The aforementioned packages were vaguely labeled to "protect his customers".
Players who returned to him after delivering all of his packages would've been told a long story by Little Mo, strikingly similar to the famous quest While Guthix Sleeps in RuneScape 3, and would've been given a pair of dragon claws.
- Little Mo has an older brother, Big Mo.
