Ed is a large spider (about the height of Finn) with a sucked-in dark-orange face and very dark-orange skin. He has eight legs, but two appear to be arms because they are shorter and he doesn't walk on them. In addition, these two arms are attached to his head; the other six are attached to his thorax. Unlike a real spider, he has three parts of his body, which are shaped like beans. He has dark-brown skin, and his eyes are yellow with black pupils.
- Barb trying to eat Ed is similar to what actual spiders do in real life. The female often consumes the male when mating.
- A spider similar to Ed is an enemy in the Game Creator, who also carries a flame sword. They are able to walk around.
