I have talked to @KlutchDecals about this.
2 Citizens stole one squid pet each from me when they were "organizing my chests"
The leader of the 3 friends blamed the person who didn't steal the pets for stealing them.
I also believe they sold the pets after acquiring them for 1k each or something like that, as one of them had $0 and now have 1k. (They were organizing my chests the whole time.)
Klutch got me this:

They left this message after I left:

Mopish = MopishGoose1630 Panda = xoxPandaGirlxox Princess = PrincessCute2
From the signs Mopish wrote, he/she tried to blame Princess for stealing the pets, but from Klutch's evidence, both Mopish and Panda stole the pets, not Princess.
I am hoping I can get either 200k back or the 2 pets.
That is all...
The only thing we couldn't understand is why 3 eggs were removed when I only had 2.
