Feature request: Option to make seekers harmless

[wackget]

I am playing the game with a young person who finds the seekers (fish eyeball octopus monster things) very scary.

Can someone please add some options to make the seekers harmless to the player?

Also an option to mute their attack sounds would be appreciated too.

Thank you.
