My Squadine night

Today I saw what kind of things Squadines usually do:

They always want to help carry stuff to any place that I wish

They always follow me around

Is easy to feed them, they love Gemo and each one eats a Gemo at three different times of the day

An interesting thing that happens when I'm going to sleep is that they don't want to sleep in my bedroom, they run away, they leave the house and they go to sleep in their underground nest. I didn't notice until this morning when I couldn't find them anywhere in the house but they were waiting for me in front of the house.
I confirm that they sleep inside their nest this night because I follow them when I turn off the light, it looks like they are afraid to be in the dark or they didn't notice when nightfall arrived.
It's odd that they are so afraid to sleep outside fo the nest because I don't see anything that could hurt them at all, there is no predator in the Korc Village, I walk for a while looking for any different Bioversal that I saw during the day... Well, there are some different Bioversals, but they don't look like they want to eat Squadines... I think.
