This is a creature with a mouth covering most of the face, It has no arms and six spider-like legs. The default variant is green in color. The creature walks upright and it's unnaturally elongated torso makes it appear menacing and unusual. The old version had a large gaping yet flat mouth with sharp teeth around all four sides and four legs. The body had 3 lines on it and the bottom of its feet was red. It was bright green in color.
- Its old rendition looks similar to Mojang's Creeper from Minecraft. It was changed due to copyright issues with Mojang.
- There are a few other enemies like the Armored Stalker that are very similar to it.
- Both of its boss variants are replaced by other bosses still in their respective levels, the boss variants are somehow still found in Arena.
- In older updates, Stalkers used to spawn in Co-op Survival, but for whatever reason in a newer update, Stalkers were removed from Co-op Survival, and the Mummy Stalker replaced the regular Stalker from appearing in Co-op Survival.
