Cute Baby is an F.O.E found on floors 1-4 of the Evil Spirit Club. This FOE will drop from the ceiling following the sound of a rattle and chase the player until they exit the room. if the player lures this F.O.E in front of a door leading into a music room, this F.O.E can be put to sleep.
Cute babies have immensely high physical power, as well as a cut resistance that makes linking tactics less viable than usual. Fortunately, they also have a hugely notable non-immunity to Hamaon, at a point where access to Hamaon should be within reach. This vulnerability is further compounded by the fact that they have a high likelihood of losing a turn should the player attack them with light magic. This weakness allows the player to not only defeat the Cute Baby, but to effectively grind off of it, harvesting a sizable roster of Personas well above level 40 and gaining a substantial level of EXP for a battle that could theoretically be ended in one turn by a one man party.
Due to the boss's sizable attack stat, equipping armor with high defense values is more important than normal.
