Wall Creeps
Wall Creeps are spider enemies that can only move on walls. They will generally try to line up with Isaac to unleash a ranged attack.
This page is about Wall Creeps added by Fiend Folio. More information about Wall Creeps in general can be found in the vanilla page.
Fried
Fried, when lined up with Isaac, will breathe out a cone of fire for a decent period of time. They will slowly shuffle to follow Isaac while firing. The fire will reach approximately 5 tiles before fading out.
Ogre Creep
Ogre Creeps will lob projectiles directly at Isaac's location which leave a 
Cobweb upon impact. If the projectile hits Isaac directly, he will be slowed for a short period of time.
Scope Creep
Scope Creeps are a fusion between Wall Creeps and 
Sniffles. Scope Creeps will fire a loose line of 5 projectiles in a straight line with the furthest 3 projectiles dealing a whole heart of damage. They will also lead their shots if Isaac is walking towards their line of sight in order to cut him off. Unlike Wall Creeps, Scope Creeps will only fire when it is lined up with Isaac.
Arcane Creep
Arcane Creeps will periodically shoot a large, slow-moving magenta projectile. When Isaac is perpendicular to one of these projectiles, it will split into 2 projectiles that accelerate for a moment to each side.
Scowl Creep
Scowl Creeps possess a red 
Tractor Beam ray in front of them. They will shoot single large and slow-moving projectiles that will always be aligned within the beam and follow the Scowl Creep's movements.
Trivia
- Ogre Creeps are based on Ogre-faced Spiders.
- Their ability to shoot Cobweb projectiles is also based on how Ogre-faced Spiders catch prey by spinning nets out of web and lunging them at insects.
- Hidden within the Ogre Creep's spritesheet is an unused frame showing a green-coloured Ogre Creep with ears referencing the animated movie character Shrek.
- Arcane Creeps were originally from the Guwah's Greatures mod and could also appear in Gehenna.
