As Finn and Jake were consumed by the baby spiders, out of nowhere came some fireballs. Finn knew who it was, but couldn't focus on that right now. In a flash, Ed and Barb were dead. So were about 88% of the baby spiders. Now free, Finn and Jake beat a hasty a retreat back to the Tree Fort, especially Finn.
As they fled, the person who had killed the spiders stood with a solemn look on her face.
"I hope...someday...we find a way to defy the elements" she said sadly.
