How do you switch between characters on the sims 2 castaway?

For PSP... To switch sims, you first have to invite them into your tribe. to do this... 1. talk to the sim until you are friendly 2. open all of the choices (for example, talk, play, nice, etc.) and choose "special" 3. choose "ask to join tribe" You can then switch with them by... 1. holding down L and the pressing the right arrow key (>) until the sim you want to be is highlighted 2. release both buttons, and you will be in the body of that sim
