[TOMT]Old point and click that took place in museum [Game]

When I was a kid I remember playing a point and click adventure game in which you played a kid who breaks into a museum at night. Some of the things from the exhibits are missing and you have to go around fixing them. I think there was a robot at some point. I believe it came on a 3.5 inch floppy disc and came out sometime in the 90s.
