Hop and Captain traitor items thread

[Technature]

As far as I am aware, the hop and captain are the only roles capable of being antagonists with no job-specific traitor items. This thread aims to fix that.
This is mostly just so random people can throw ideas around, but I have some ideas of my own.

Hop-Specific: Bioterror sponge capsules. Like the biotoys capsules you can get from QM right now, but instead of spawning harmless critters, it spawns horrible monsters like wendingos, yetis, and space bears.

hop-specific: assistant sponge capsules that use robust ai. just fill the halls with generic (think admin default spawn) assistants with a thirst for chaos and blood

Oh Oh OH!

A grenade that spawns 5 of this with water.

Balance, they aren't friendly to their user either, so when you accidentally come back they start beating the shit out of you.
