Hopper Spider is a passive item in Glacier's Laboratory, a mod for The Binding of Isaac.

Red Spiders and Big Spiders now attempt to leap toward Isaac, and they will periodically ambush him when he enters uncleared rooms.

Every Blue Spider now jumps upward from time to time, each jump multiplies its damage by 1 + 0.3 * JumpedTimes and reaches maximun damage after 10th jump.

Killing a non-spider enemy has a 33% chance to spawn a Red Spider, Big Spider or Blue Spider.

If Isaac has multiple copies of the item:
• When damaged by Blue Spider, Red Spiders and Big Spiders become friendly instead.
• For other enemies damaged by Blue Spider, they are inflicted by poison that deals DamageStat x AdditionalCopies damage to them 6 times.

This item contributes towards the Spider Baby transformation. Collecting 3 items from this set will spawn a spider familiar that applies random status effects when it comes in contact with enemies.
