A high-level Octopus Cat with the Curse Immunity Talent makes this stage much easier, for it can not only avoid the Relic Doge Base's curse and thus tank an absurd amount of hits from all of the enemies, but is also able to block the Waves from Pigeon de Sable and Bun Bun Symbiote.
- Like all Theatre of Fear stages, Normal Activity is named after a horror movie, in this case Paranormal Activity.
