Add a black tentacle that pulls you into the hole instead of the giant worm

That means that he'd have to add a whole new animation for that. I like Egezkutor's idea more, as the spike animation already exists. He only needs to have it for when a person falls into the void. The current problem with the worms is that they are able to kill you if you're too close to the edge of the floor, a problem that wouldn't exist if you had the spikes.

This is just my opinion if you do not like it, it's okay

I agree with v2, but definitely creative.
