Does anyone know where I could find a list of all the mininons that exist and that says how many there is? :)

On both subetalodge and subetahq they have item lists, where you could find minions. Subetalodge also has a thing called 'minionizer' where the minions are divided by certain traits and categories. ^_^

Oh, cool! Thanks, that helped a lot, actually :)

You're welcome. Happy to be able to help. :)
