You should make a creature (doesn’t have to be aggressive) that enters the base and maybe you could even make it try to replicate base furniture (kinda like an octopus replicates ocean objects), and make the security camera functional and motion detecting so when you are cruising along in the tadpole you get a creepy motion detected at base alert then you have to find it and scare it away or something, i personally feel like that would be a fun scare

Below Zero’s triops evolved from an early sea monkey design that would invade your base and steal stuff. I don’t feel the security camera would add much, but I do like the idea of finding something small and squishy making off with a battery or something.
I just thought it would be a fun creepy Easter egg plus they already have security cameras designed it would be interesting to put them places kinda like trail cameras, especially with how much they are making creatures interact

I think Itd work if they dont do anything too intrusive like stealing stuff. Maybe it could be like a crab or octopus that feeds off of electrcicty, so when you come back your lights are all off and its scary, only for it to be a tiny crab sucking on your generator
