Baby Long Legs

Baby Long Legs quickly run away from Isaac and spawn Spiders from time to time. Usually, they can spawn a maximum of 3 Spiders. They run around erratically when Isaac is nearby, which can be dangerous especially if they are Champions, as Baby Long Legs can be one of the fastest enemies in the game. As such, there is a chance that it will bump into Isaac and therefore deal touch damage to him.

Small Baby Long Legs
The Small Baby Long Legs is a tiny variant of Baby Long Legs that simultaneously spawns Sacks along with a small puddle of slowing White Creep. The Sacks it spawns start at around half health and take a while to regenerate fully, so they can usually be destroyed before they start spawning Spiders.
