If you want to.
get the beaver to have full trust with you, and it will build the dam by itself.
There are quite a few ways, if you wish to break up with the Sim you are with, and like another Sim, flirt and build a romance relationship with another Sim while the Sim you're "going steady" with is over. If you don't like any other Sims, then there are certain things you can do to annoy them, experiment and see which one annoys the Sim the most. If this is not what you meant and that you're trying to build a higher relationship, then as I mentioned before, experiment with the Sim you're "going steady" with to see what the Sim likes.
Its one of the sections in the build mode of the "build/buy" mode which u get to by pressing select.
Build up the relationship meter with the Sim you want to move in with you by performing lots of actions with that Sim and talking to that Sim often. Eventually, you will be given the option to Propose and then to Move In. When you ask that Sim to move in, they will agree to it if they like you enough.
The easiest way is to build a pool with a ladder to go with it. Then, have your sim get in to the pool using the ladder. When your sim is comfortably swimming, remove the ladder. That way, that cannot get out. Fast forward the time, and eventually your sim will drown and die.
Go to Build Mode and click Create Pool.
build a pool if you dont have one and attach the stairs to get out (i dont know what they are called) once your sim gets in the pool remove the stairs and in about 8 hour your sim is dead.
