There are 4 minigames you need for this achievement. They pop up randomly after you get killed by any of the animatronics.
The 4 minigames are:
-SAVE THEM -consists of Freddy following the puppet and can start in any which room (there are multiple variations of this minigame, but since I am currently at 75%, I'm assuming you just need any which one of it).
-Give Gifts, Give Life -consists of the puppet giving gifts and life to the animatronics, followed by a jump scare.
-Take Cake to the Children -consists of Freddy taking cake to children while the Purple Man shows up outside in a car and presumably kills another child who is locked out.
-Foxy Go! Go! Go! -consists of Foxy running into a room full of children 3 times, the third of which will show all the children dead after the purple man shows up backstage.
These are the 4 different minigames that can show up following jump scares.
