Behavior

Daddy Long Legs' head hangs down stationary and can perform the following attacks:

Raises his head, making it invulnerable, and stomps the ground in random locations around the room 4 times in quick succession. One of these legs will always stomp on top of Isaac's position.
- The appendages that he stomps with can be attacked to damage him.
Lifts his head off-screen and stomps the ground 4 times at regular intervals on top of Isaac's position. At the end of the 4 stomps, he slams his head down quickly, shooting out 8 projectiles in all directions. He can only slam his head down along a horizontal plane across the center of the room and slams it down close to Isaac's position.
- Occasionally performs a fifth stomp before slamming his head down.
- The appendages that he stomps with can be attacked to damage him.
Spits out 2-3 Spiders.
- These spiders can be killed by Daddy Long Legs' stomps and head slam.

Daddy Long Legs' foot stomp and head slam deal a whole heart of contact damage.

The passive item Daddy Longlegs is a familiar form of this boss, stomping enemies to assist Isaac. The familiar will even attack the Daddy Long Legs.
Like Mom's stomp, his stomp deals explosive damage. On rooms where Daddy Long Legs is treated as a degraded Boss, they can be used to blow open doors.

Daddy Long Legs was added in the Wrath of the Lamb DLC for the original The Binding of Isaac.
- In the original Binding of Isaac, Daddy Long Legs could be encountered in Necropolis.
Daddy Long Legs's appendages consist of 2 hands and 2 legs; he will use each of them once in his stomping attacks.
- Only 3 appendages visually appear to be connected to his head despite him having 4.
Daddy Long Legs is a colloquialism for various types of arachnids including Opiliones and Pholcidae.
Triachnid is his alternative version.
His limbs are also used by the Daddy Longlegs item. However, the item's take on his limbs behaves differently.

Bug!	During the mass-stomp attack, the player will take damage before the animation even begins, making it impossible to dodge.

Bug!	During the mass-stomp attack, if the player deals damage to one of the legs that would normally kill a full health Daddy Long Legs, it will cause the leg to die as a separate Daddy Long Legs. This will not damage the boss at all.

Bug!	If you freeze one of Daddy Long Legs's legs, then kill Daddy Long Legs while a Spider is still alive, then kill the Spider, the boss fight music won't stop. This is fixed if Isaac leaves the room and then re-enters again.
