Imaginary Friend stuck in doll form

I think I can answer this pretty easily, Imaginary Friend Doll does come alive, but how it comes a live is important. Imaginary Friend Dolls are service sims when they are in the imaginary friend form. Whenever the children are sleeping or away from the home lot they will not come alive. Sims that have the second form of imaginary friends can see other sims imaginary friend doll. Once the doll is changed to IF stage 2 the doll is connected to the Sim and the neiborhood and can't change neiborhoods because the IF friend is not a member of the household but is treated as a visiting friend so it goes to the service house during times it is in doll form and returns to a toy. If the IF doll in stage 2 is not turned real after the kid that spawned the IF friend dies the IF doll will be available again for its magical power. If a sim gifts his doll to another member of the family the IF doll will live in the service household until it dies, but won't be connected to the doll anymore but spawn another form of the doll the same age as gifted. If the doll is just setting around and if not connected to any previous sim the doll should display magical powers like the magic gnome, if not the doll IF is still connected to a stage 2 friend that can only be called by the Sim that originally had the doll. The IF friend Doll stage 2 dies when the sim dies that spawned his IF friend. The IF doll Sim stays at the Service household until the IF is summoned by the kid by interacting with it or when the kid wakes up and comes on lot. The doll returns to doll form when kid leaves lot. During the doll dormant stage the doll has no magic but can still give the IF moodlet for playing with it and give social interaction to both toddlers and kids.

Edit: I forgot to mention if the doll has a strong enough relationship with the kid you can do the test on his birthday put the doll a ways away from the birthday cake when the toddler blows out the candles the doll in toy form should magically teleport to the kids birthday cake and when he ages the doll will age too and within a hour the doll should age into a IF friend stage 2 the same age as the sim who imagined it and will always be the same age as that sim.
