The toy mouse is a clockwork item that players can wind up and release, whereupon it will move around on the floor. If the player can catch it before it stops moving, they will gain 3 Agility experience. Despite being a members item, members used to be able to use it on a non-members server. However, this is no longer possible.
Members can make a toy mouse at a crafting table 4 (Construction level 42) in the workshop of a player-owned house. They need level 33 Crafting to construct the mouse, and gain 15 experience in doing so. The raw materials needed are a clockwork (made from a steel bar at any crafting table) and one ordinary plank. Toy mice can also be picked up by Ava’s accumulator; the chance of this occurring is 1/2,000.
Cats can chase these clockwork mice. If they catch them they will eat them and the clockwork mouse will be lost. In addition clockwork cats can chase clockwork mice, just like regular cats chase rats.
Clockwork mice used to be a great source of Agility experience since players could gain 15 experience points for trying to pick up a mouse, whether they caught it or not. Since players with low Agility levels would frequently fail to catch the mouse, they could repeatedly attempt to pick them up and gain very fast experience.
The toy mouse received a substantial nerf on 21 March 2013, and is no longer a great source of Agility experience.
