A family album is a feature exclusive to Tomodachi Life. After a married couple's baby grows up and either moves into an apartment or goes off to travel, the father gives the player an album showing pictures and clips of the family's happy times together, as the game's credits roll. Family albums are accessible through the town hall's child info.
Up to 50 albums can be kept at once. Once a new child has grown up, its album will replace the oldest album unlocked. The player can lock the albums it likes the best; but only 49 can be locked. It is also best to take pictures of the unlocked albums so they can be remembered.

After the last picture is displayed, the view fades to white as the child's giggle is heard. Then a home movie of the family at the park is shown. The child skips in place as the father (who is filming the movie) says, "Hey, [Child]!". The child looks up and rushes off, the mother looking on in the background. The child peeks in from the side and as the father says, "Come here!", the child giggles and hops away, before charging at the camera and doing a little dance. The father says, "You're so funny!", which amuses the child as it hops off, before quickly returning and jumping at the screen as the father says, "Ha ha ha!". The child continues jumping as the view fades to white.
