Guide Objects


Poisson (French for "Fish") was a predecessor to Aaaah! posted on Extinction, with mechanics similar to Transformice in terms of gameplay and objects. It was only online for a few months until Transformice was released. Instead of mice looking for cheese, in Poisson there were fish trying to get back into a water bowl. The fish, however, had the unfortunate tendency to slide all over the place. Like Aaaah!, it featured multiplayer gameplay with a guide who was supposed to help the fish to the fishbowl. However, instead of drawing a path to the objective, the guide in Fish had to place physical objects in the world. In addition, the guide had no physical presence and could place objects anywhere on the map.

The objects available were very similar to the ones in Transformice (see picture). All the original Transformice objects plus some additional ones (notably an Up Cannon gift in the first versions of Transformice) were available to the guide in Fish. Unlike Transformice, Fish listed all of the available anchors in the object pool, and did not have as many anchors available as Transformice does. In addition, the Guide had the ability to stop time for a few seconds, which made placing objects much easier without having to worry about the hopping fish. Interestingly, the fish always started on the bottom left and had to reach a bowl on the top right.

Differences to Transformice

While similar, Poisson has some noticeable differences compared to Transformice:

  • An "Up" cannonball.
  • You control Fish.png fish going to a Bowl.png bowl.
  • The bowl is always on the top right.
