Doctor Heart is an NPC in Adopt Me!. She serves the purpose of healing the Babies and pets in a family through fulfilling the 'Sick' ailment. She can be found in the Hospital along with the other NPC, Nurse Knee.
Doctor Heart has brown hair with a bun tied by a red bow on the right side of her hair, a doctor’s coat, a head mirror on her head, and a mask resembling her job as a doctor.
The following is the dialogue which Doctor Heart speaks when a player talks to her:
"It's nice to see you again, [username]!" Then, a pop-up appears on the player's screen stating, 'Ask Doctor Heart to heal your family?' with two options; 'Yes' and 'No'.
When the 'Yes' option is selected, Doctor Heart says,
"Healing your family..." Then, a white halo, similar to a loading circle, appears on top of the heads of all players in the room, which satisfies the 'Sick' ailment should a player have the task.
However, if the 'No' option is selected, she says,
"Come back if you ever feel sick!"
