|“||That's my twin sister, Abigail.||”|
Abigail is the Ghost of Wendy's dead twin sister. She can be summoned with Abigail's Flower, Wendy's exclusive starting item. Abigail will defend herself and Wendy against attacking Mobs, and will attack anything that Wendy attacks (even if Wendy cancels the attack).
Abigail will despawn into her flower if she loses all of her health. Abigail does more damage during dusk, and significantly more damage during night.
Abigail has a fast, periodic, area-of-effect attack that damages all hostiles within a small radius. If she attacks mobs that spawn in groups such as Spiders or Beefalo, she will incite the whole group. Abigail can also damage Spider Dens, Beehives, and Killer Bee Hives. She will not automatically attack anything (except for neutral Treeguards); mobs have to attack her first or become a threat to Wendy. Abigail will stop attacking after a few seconds if mobs are not targeting her or Wendy, or if Wendy moves a large distance away (about two screens).
When traveling, Abigail follows Wendy, always maintaining a small distance. Abigail can keep up with Wendy as long as she stays off Roads and Cobblestones and doesn't use a Walking Cane. Abigail will teleport off screen near Wendy if the player goes too far away from her.
If Wendy intentionally attacks Abigail using the CTRL+Click option, Abigail will "die" in one hit and leave her flower on the ground. This can be used as a method to dismiss her at will.
- Abigail can effectively stun-lock groups of Spiders while taking very little damage herself. Use this to your advantage when attacking Spider Dens; though be aware that Spider Warriors will not be affected by this.
- The player can use healing items on Abigail to bring her health back up after an attack. She will have a sad look when she is near death, so use them on her if enemies are still nearby.
- Abigail regenerates health at 1 HP per second and can heal herself to full over time if kept out of combat long enough. It takes almost 10 minutes for Abigail to regenerate from 1 HP to her full 600 HP.
- Crows and other flying birds will flee before Abigail can attack. Rabbits on the other hand can be outrun by Abigail and get hit by her attack. It will take multiple hits to kill a rabbit in daylight though as Abigail does only 10 damage.
- When hunting a Koalefant or its Winter counterpart, Abigail can help draw its attention. By clicking on the Koalefant while the Attack command shows, Abigail will head to its position and engage it in combat, causing it to aggro on Abigail. One can then attack the Koalefant, allowing the player to avoid crafting a ranged weapon or chasing the Koalefant into a corner.
- Abigail's AoE attack can easily take out Beehives. Abigail will attack any Bees that come out after attacking a Beehive or gathering Honey from a Bee Box. During the day, it takes a while to kill them all. Use this opportunity to catch more Bees with a Bug Net while they are stun-locked and use them for Bee Mines or more Bee Boxes. If one does not want Abigail to attack the Bees, place the Bee Boxes a good distance away from camp.
- Take advantage of Abigail's increased damage during dusk and night. She is twice as strong at dusk, and four times as strong during night.
- Abigail is no match against herds of Beefalo in heat. If one makes a Beefalo pen, seal it well or keep it far from camp to prevent any mishaps with Abigail.
- A useful way to summon Abigail is to stand next to a nearby flower and hit a Butterfly when it spawns. These creatures can be killed in one hit while unarmed and doing so will be enough for the blood pact.
- One can also spawn Abigail easily by using a Fleshy Bulb in the Winter. The Lureplant it spawns can be killed and placed over and over again to spawn Abigail; and while its Eyeplants won't bother you during the cold season, they can also be used to summon Abigail in warmer seasons.
- During dusk, Pigs who do not have a home to hide in will see Abigail as a source of light and follow her.
- When Abigail gets close to Wendy you can hear her whisper.
- Kevin has revealed that Abigail is jealous of Chester, and she used to kill Chester. This feature was removed in the Doorway to Adventure Update.
- Before the Strange New Powers update, Abigail used to appear during the night (disappearing at day) at least once every 3 nights, but this was changed to her current method of spawning. Since Abigail no longer despawns at day, she can be around the player for extended periods of time. As a result, her ghostly voice was made much more quiet.
- Abigail's default damage is actually 20 in the lua files; it is halved during daytime due to the light, rather than growing stronger at dusk.
- It was said by Kevin during a live stream that Abigail died under mysterious circumstances. 
- Summoning Abigail used to cost 25 sanity, but as of the Moderately Friendly Update, the cost had doubled to 50.
- In previous versions of Don't Starve, Abigail would harm Wendy and other mobs when she got too close.
- Other Characters have quotes for examining Abigail, since they could examine her when changing characters with the Tent was possible.
- Wendy's ghost in Don't Starve Together is an almost exact horizontally flipped copy of Abigail. The only difference is the color of the flower, which is yellow, despite Wendy's flower being red in life.
- Abigail can fly out over water and get stuck. This causes her to sit in the same spot. If however the character walks close to her she will go further out over the water, but not come back to land. One way to get her back is to travel in a Worm Hole. She will then spawn next to the player at the end of the Worm Hole's animation.
- Abigail can be duplicated if Wendy dies in a Cave. When the player respawns with a Touch Stone, they will have Abigail's Flower in their inventory. The player must wait two days and summon Abigail before re-entering the Cave. Once Abigail has been summoned, the player must return to the cave, where they will find another Abigail waiting for them. Warning: If Wendy enters the cave with Abigail's Flower in her inventory, all instances of Abigail will be erased.
