Note: For best results, put in new batteries after your Hatchimals hatches. Replacement of batteries must be done by adults.
- Open the battery doors underneath your Hatchimals Mystery Hatch using a screwdriver.
- If used batteries are present, remove these batteries from the unit.
- Replace battery doors securely.
You can tell if your Hatchimals Mystery Hatch is low on batteries when the lights flash red and beep.
