The Ghost Trap is a predator native to Blue Moon. It has got a radial symmetric body with several tentacles to catch Caped Stalkers and take them to the stomach. Along with 5(?) muscly tentacles, they have many more thin, glowing tentacles that its prey get tangled in. After taken to the trap's stomach its prey faces a slow, painful death; dissolving in a bath of acid.
The ghost trap's gushing, red 'mouth' can be covered by an opposable 'lid', as seen in the bottom picture.
