While "Entity E" is not a standard named animatronic in the base game (which includes Freddy, Bonnie, Chica, Foxy, Puppet, and Golden Freddy), the "E" script might be used to:

: Developers use the ProximityPrompt object to detect when a player is near an interactive item.

: By default, the KeyboardKeyCode for these prompts is often set to E .

The "E to Teleport" mechanism is a common Roblox Studio function used for doors, gates, or area transitions.
