There are spiders, spiderlings (from eggs after sex with a spider), duo spiderlings, this wall spider thing with 2 scenes and a like flower zombie runner thing. Allongside that the paid version gives the option to view the gallery after beating the game.

Oh never mind it seems like it had changed since i played the new update but yes uh the paid version now does only include the gallery after finishing the game and the death animations. This does mean that if you have the newest version after the spiders you should see that flower runner zombie thing.
